Aye I've made a drone carrier before, it was for a mod I'm really not sure I'll ever release, here's the sprite I kitbashed for it:
It fielded 6 wasps (converted to drones like the old wasp wing), regenerated them somewhat slowly and carried 3 spares, they attack within a reasonable range so the carrier was more of a support ship than anything. To balance them for that exact reason its firepower is kind of weak, the one medium slot is missile and pointing backwards, its flux efficiency is also quite poor. In retrospect it's still pretty overpowered by itself as I made it as fast as the Medusa, so it probably should have been slower. Otherwise though, the drones were still not particularly effective at much beyond PD and slowly whittling down ships with narrow-ish omni shields so there's that.
Also: I can't seem to download your mod, it just gives me a big grey blank screen below a toolbar-like thing.
