I would be into either of those, though I think the kotor 2 characters might have somewhat limited recognition and appeal now (but I am really glad we at least got Visas, Traya, Nihilus, and Sion). Still, Mandalore would fit nicely into the Mandalorian faction, and it'd be good to give Visas a thematic home.
I do think that the clone commandos would be very well received, since people love clones nowadays. But it might be hard to differentiate them from Bad Batch. Plus, the commandos were only a team of 4. (Maybe they have bonuses for using only a squad of 4?)
I'm an old man—I mostly want Galactic Civil War or Legends things. (General Rieekan to synergize with HRSoldier, ROLO, CHOLO? A small rework to give Lobot and Lando some synergy? 4-LOM and Zuckuss? LS Mara and Talon Karrde? Winter? Corran Horn to lift Wedge? Tycho Celchu as A-Wing pilot?)
