Would it be possible for Brainy as Lonestar to take a very passive role and maybe sneak them some useful tech to help them do this? (pending mod approval, of course)

The caveat is I can't really have him caught because he's also doing other stuff that he'd get executed for like allying with the rebel hacker but that also means he wouldn't actively be on the mission to be caught and the discovery of the tech would start to make him a target anyway, even though no one would know who he really was.

Giving them a useful doodad like a password cracker or something to bypass a retinal scanner is a nice indirect way he can help though.
