No thanks. It'll just become the opposite problem at that point. The correct solution is to just open up cross-faction play, keep PvP the exact same, but allow any/all PvE content(open world, M+, raids) to be done regardless of faction. And if you turn on Warmode it disables cross faction play. It's not a complicated fix and the reality is there are very strong Alliance racials that some specs would rather have, but it's not realistic that a whole guild is willing to swap alliance to gimp themselves on recruitment and other activities that require grouping just for mostly even racials.
