Star Fox fans aren't quite as fussy as Metroid fans I don't think.
Mario/Metroid/Zelda are the three Nintendo IP where you really have to be careful what you change and why.
Star Fox has more leeway, but as long as Platinum would be smart enough to keep the action in the aircraft and not stray towards land based missions, I think they'd be fine.
If not Star Fox I think Kid Icarus with Sakurai overseeing wouldn't be bad for Platinum, though sadly I think Nintendo is going to cut bait.
