I've always dreamed of this, too. Something like the T3-M4 sequences in KOTOR, but with an expansive hacking element. I think there's lots of opportunity to use astromech droids as the stars of stealth games. In-universe, most humanoids tend to ignore astromechs as unimportant pencil-pushers, and so the cat-and-mouse of most modern stealth games (just wait 'till the alarm icon ticks down, and you're good) would be narratively apropos.
