I'm for hanging on to as much as possible.
There's no point hanging on to a base if we're not going to staff it, right? At which point being able to disguise our new recruits as Imperials could be very handy - or not, but we'll have the option!
It may not help us directly, but in the future that's nine bodies we can expect to smuggle in to Imperial controlled areas beyond whatever we as a party do.
Worst case scenario, Orun can take the suits of stormtrooper armor and use them as shells for droids. Maybe with a clone wars era droid control unit installed at the base, we could even conduct minor operations without any of us physically being there at all. Hmmmm...
In the mean time Orun will start cannibalizing those bikes and the second walker to get us as operational as possible... and add the "Droid brain" upgrade to his wishlist for that walker.
(Viva la droid rebellion! ...at least until we get cloning equipment.)
