Season 1&2 Ahsoka is not great I'll grant, but she is much better in 3-5. Besides the Muunilinst 10 didn't actually do much past Muunilinst. Hypori is the last recorded battle the group as a whole participated in. Fordo would not be a bad option though.
Still would like them in mostly as fan service, but they are pretty much only that. Just a superior ARC Commando Squad.
So I've been thinking and the only Clone heroes I can think of, Delta Squad (obious), Fordo / Munnilist 10, Rex (I kinda think he was good from my bad memory of the Clone Wars), Cody (because of his one scene in the original shorts, trolling Kenobi with the jet pack), and the anonymous Five Oh First soldier that's the protagonist of BF2.
