Clearly the playing group can't be split that much or they would have got rid of Wallace, the situation would have been impossible to carry on with Wallace in charge if the split was that bad. Looks like the main instigators were those who weren't playing and probably don't deserve to ever play again, certainly not those you'd be paying any attention to anyway.
As far as I'm concerned, Simmonds, King & Johnson need to be delisted immediately. No great loss there on current form. Newman should stand down as captain, but not be dropped, I'll give him the benefit of the doubt for being naive and pressured by his ex-captain and backing the wrong horse, so he should keep playing, but not as captain.
