And as I demonstrated above with the Droid Tie Fighter, systems made WITHOUT those things are actually more expensive. Also the Gs angle is a waste of your time as we already know that Star Wars has inertial dampeners that negate G forces as a factor. As demonstrated by Porkins slamming into the Death Star because he had his on full power and couldn't feel that he was descending into the Death Star's surface. (Canon from the novels I believe)
Fair enough. However, I do not accept your analysis of pricing as we have no knowledge of SW economics, so it is unfair to say that all snubfighters cost less than drones. And you only provided one vessel, you did not provide enough data to prove that all drone vessels inside SW cost more than piloted ships.
Yes, and those fighters have missiles for exactly that purpose.
Missiles which are incapable of dealing damage on the scale of an ICBM, hence your point is moot. A proton torpedo would not have the same yield as a FTL missile.
Except that you are not just in essence, but in fact, adding an entire second drive system, NOW you're adding a seperate generator, PLUS this system has to have a nav computer in order to use the FTL drive at all.
I'm only adding a second generator. This missile would already have two distinct drives, one for sublight maneuvers and one for FTL, just as any normal starfighter. Also, from Episode IV, Han's description of the hyperdrive suggests it is entirely possible to engage an FTL jump without calculating it. I will assume that the drive accelerates the ship linearly and adjusts course to evade celestial bodies. Though, as I am EU illiterate, could you tell me if this assumption is accurate? Or does it work like BP's interpretation of subspace, where activating a subspace motivator without a properly calculated destination could spit you out anywhere? If my assumption is accurate, since this missile attacks at close ranges, there is no need for it to make corrections to its FTL jump, and thus it does not need the computers required to make the calculations required for long-range FTL jumps.
Oh and then there is the fact that the Hyperdrive appears to UTTERLY DESTROY any factor of relativity or kinetic energy.

That is THREE Star Destroyers leaving Hyperspace straight into the Executor's shields.
Uh.... it says cruisers. I never read the comic that came from, so did they mean Star Destroyers? As far as I know, SW cruisers are smaller than destroyers. Assuming that they got their terminology right (unlikely), that's three
cruisers ramming into the Executor, not three Star Destroyers. Also, they are not travelling at relativistic speeds. They dropped out of Hyperspace and decelerated. While it is impressive that the executor's shields managed to protect it against that kind of bombardment, it does not accurately represent what an FTL missile will do. I don't think the executor just shrugged this impact off. I would expect the Executor's shields to be significantly weakened after having to repel that much energy. I concede that this does demonstrate that to take the Executor out with FTL missiles, you would need a ridiculously large number. However, this missile was never intended for use against an SSD. It is simply a powerful anti-capital weapon meant for use against cruisers and destroyers.
The problem isn't the comparison. The problem is the proposal to design an utterly ridiculously expensive weapons system that all evidence shows won't work anyway instead of what they actually do, which is just field more fighters with missiles and bombs.
You have not convinced me this weapon will not work. You've shown several scenarios where it will not be effective, but you have yet to demonstrate that an object traveling faster than light ramming into another will not severely weaken and/or destroy the target. You have also not convinced me that this weapon is cost ineffective. Granted, when Han discusses the jump in Ep. IV, his main concern is bumping into a star. We know his ship would be pulled out of hyperspace by the gravity well, but he also mentions flying through a supernova. Supernovas are not gravity-rich environments, which means that while you are in Hyperspace you can collide with Realspace objects.
The problem with what you said above is that it is blatantly false. The governments of the world designed an utterly ridiculously expensive weapon system that worked so well, they went and build tens of thousands more of them. And then they fielded some more fighters, just in case. Your example fails in that the ICBM and Cruise Missile are not expensive, ineffective weapons. They are expensive, yet incredibly effective, do exactly what they are meant to do, and do it with an efficiency unrivaled in the history of warfare.
Now if your proposal was for a planetary-strike missile (for unshielded planets) then i'd agree with you if you could somehow bypass the mass-shadow issue (or instead of just decelerating to slow decelerate to just under C)
But as a proposed weapon against starships all evidence points towards them being nothing short of useless.
Hmm... targeting a planet with said missile would be interesting indeed. Entering the atmosphere traveling FTL... what would that do? Would it be the Tunguska Event x100?
Still haven't convinced me this weapon is useless. Unsuitable for certain situations? Yes. Using it against a SSD is not a very good idea. Using it against an SD is.
