Indeed, Mairaath remembers.
Anyway, I admit it is a crazy idea. It would, of course, be useless to restore a ship used for suicide runs, so I don't see how that cost investment would happen (at all, I don't spend that much on regular capitals either). Nevertheless while I see the value in making it a better ship, its purpose (I think) is not to be viable, but to provide an alternative as nothing viable is readily available to Pathers. It would (and I guess it should) struggle against similar opponents.
Perhaps giving it two extra fighter bays but also some fighter debuff could pimp it up a bit? Like converted hangars, but with less extra cost for fighters.
As for the mechanics... well, this is a flavour ship. Mechanics-wise there are a lot of better options, which require less tinkering (and investment) to make them viable.
