It depends, I think Shenmue 3 if given to AM2, Yu was given the control he needed and the game was given enough time in the oven? I think it could be great. Streets of Rage would be a tough one to revive well just because the beat em up genre has struggled so much since its peak. Golden Axe was handed to an awful team but to be faithful to the original would face the same issues SoR would. It'd be hard to please SoR fans like myself because I'd want a more simplistic well executed beat em up like SoR2 and to do a beat em up, nowadays, it seems like you have to add things like equipment. Even then, the only new beat em up success stories that come to mind are Castle Crashers and Scott Pilgrim.
Shinobi on 3DS was a solid game imo, not as good as the Genesis titles but I liked it. People forget Shinobi was for the most part a B-tier SEGA franchise, it had some great games but it was also over-utilized as an IP on Mega Drive/Genesis imo. The Saturn entry (legions) was also rather disappointing. Jet Set Radio is a toughie because a new game would likely be way too easy to even be good and take more after JSRF vs. JSR, while JSRF is a good game it has no real challenge. Ideally they'd mate the more understandable JSRF controls to the graffiti and time limits of the original.
Out of all these games the one I'd be most hesitant of is JSR, the first is arguably the best 3D platformer ever, Shenmue 1 and 2 are my favorite games ever but I feel more confident SEGA of today could handle Shenmue 3 than JSR3.
