Pah! I have something much funnier!
All you need is another ship that should be small and manouverable (Ulysses, Elysium).
That ship must be docked with the Arcadia... And then... Well...
You'll see 
It just takes longer 
Back a few years ago I tried Styxx's original Apocalypse model which is a 20KM long warship and made a dock port...and then had a Argo attach to it and then warp into subspace. Took a good long while for the whole thing to be dragged into subspace. Hilarious 
You misunderstood me

What I meant was:
The Arcadia gets moved by the other ship...
Not only when warping out...
This way the Arcadia can do amazing spins and, of course, it can fly very fast

And if you can give the docked ship the order to attack something, all the turrets of the Arcadia are firing when in range...
Oh.. And of course the Arcadia is a great shield

Also funny: You can create whole ship-"clusters" with docking!
Especially with the Argo! How many dockpoints does it have? Seven?

Oh yeah... Here's a mission I made...
You see: I've already played with that
