I don't think Jawgemo would fit well on G2
SEN could really go in a number of directions if Sacy leaves, N4RRATE is a good choice though
I think Demon1 stays on NRG, Verno would be a good replacement for crashies though.
Victor is really not much of an upgrade over Asuna IMO, but I suppose that works for 100T. I would keep Asuna though.
I agree C9 could do a massive roster change and rebuilding around OXY is good, but with money as an issue idk if they can afford a whole new roster practically. Even so, I wouldn't go for XXIF.
Bruh what is this team for EG lmao? Hot take but EG's current roster is actually good, and it definitely clears that new roster.
IMO:
G2: No changes, or Saya for icy
SEN: Ideal Sacy replacements: Verno, Brawk, crashies, narrate (if he's playing in NA again), but SEN could also go the Duelist route and put zekken on initiators. Actually, the narrate pick might lowkey be the best since you could go either way.
NRG: Demon1 back, and get a replacement for crashes (Verno/Brawk/narrate, etc.)
100T: No changes
C9: Assuming money is an issue, keep OXY, Runi, and moose, pick up an IGL/smokes (ex. OXY, Mitch/Flyuh, Runi, moose, Marved)
EG: I don't think EG needs a change, but (+yay, -Apoth) would be a win-win for both sides if it were to happen.
