Mods like GG and the competitive edition are the works of individuals. Not trying to judge them, just saying they are done by one guy.
A project involving so many people and undergoing so many processes will be able to address a wide variety of issues and resolve the concerns of the concerns of the whole player base, since different people with different tastes and preferences are involved.
Ok, I really like your idea.
But to be perfectly honest:
adress variety of issues and resolve the concerns of the concerns of the whole player base
<-- this is the problem of CoH2 Balance. If you perfectly balance 1v1, you might wreck the balance of team game modes.. and the other way around. (Well okay, any game mode's balance is broken atm, at least as soon as USF is involved
)
To come back to your question: I doubt that I fit in such a team because I can give advice only from the perspective of a 2v2 player.
+ I would prefer more harsh changes in CoH2, like removing auto-fire ability from all mortars in this game and make all indirect fire units (including mortars) do 100% friendly fire damage --> might end in a disaster
