Lose the caps, if you're halting slave transports then I see absolutely no need to have capital ships.
Colonial remnant is also likely to take over the capital ships, and img probably wont get replacements (because it's a soddin' mining corp), I'd probably just use rocs and eagles too, for the same reason, ravens talon too I suppose.
IMG is a bretonian corp, so you could use some Bretonian ships (mainly transports) like the clydesdale or percheon (both awesome) for slave liberation. Special request for other things perhaps too.
I know IMG is hostile to BMM, but if they're hostile because of BMM's harsh reputation and not just corp competetion, BMM does not involve itself in slavery whatseover, and it's actually not that bad as far as treatment of workers (right, they die young, but they die rich). You are verrry unlikely to get into a firefight with BMM, the hostility disco evolved into has never materialised in game, IMG is too close to bretonia it makes no sense, Like GMG shooting KNF really.
I see you put daumann hostile, which some might not have noticed, they seem to be up on slavery. Depending on how you look at it, hessians might not be trusted with slaves either, using them to further their own goals, providing manpower to SCRA and conscripting the slaves to fight the corsairs, perhaps having them work on the planet in 47 (as regular miners).
