Probably a good idea. If the player is doing something so bad that they need booting from the tournament then it's probably chess.com staff who should be doing that rather than tournament directors.
However, if you're finding that chess.com staff are too busy to deal with this kind of request, then continue to delegate that to tournament directors, as you now do.
Currently, Tournament Directors can remove players both during registration and even between rounds of an event that's already started.
We're considering making it so that the 2nd thing (booting a player during a tournament) is impossible.
Bad idea? Good idea?
