First things first: Zuckuss with a RecSpec sounds great. Second, I have a bit of a gripe about IG-88 B. It's just a wording thing though. You can't take free actions when stressed, so his ability is kinda wonky. I know cards can bend the rules, but it seems more consistent to just change the wording around a bit to avoid that whole nice.
Overall, nicely done. These could easily be playable.
Thanks. Does this wording sound better?
"When you perform a red maneuver, you do not receive a stress token. You may perform a boost or barrel roll action, then receive 1 stress token."
