We all know that plain, normal un-modded FS do not fare well with ground attack missions [ultimate proof of this is fact that they do not exist in game]. But, as they are rather cool, I got a little, interesting idea.
What if somebody could model a... small moon, with ground base on its surface, and subsystems acting as buildings, and turrets acting as... turrets, of course? [maybe some unholy combination to get stationary tank with gun tracking player] It will be similiar to fancy asteroid base with additions making it far more similiar to 'normal' moon with 'normal' ground base. It will also have tons of HP, as moon isn't something you can easily destroy.

With few docking bays, you could even make tiny planetary invasion, with capship flying near surface and smiting enemy with beam cannons, and all that cool stuff.
Objectives could be fairly easy to make.
If somebody already made it, or tried and failed miserably, tell me about this.
If AI is too stupid for this kind of work, it can be always made as multiplayer mission, where defenders need to, for example, stop attackers from destroying heavy beam cannons, and if they fail, destroy enemy capship that jumped in and stop landing crafts from capturing base.
So, what do you think about this idea? I plan to use it in my campaning, Red Tide, and I want some opinions.
BTW, what happened to Planetary Assault mod? Is it dead? [Campaning Watch had not been updated for about 2 years, after all]
