Well that's boring.. and nowhere near descriptive enough. As fans I say it is our duty to help name this new combined universe, to help endear it to the company and to we fellowship of fans.
My Nomination goes for: Marvel's Abject Serial Transforming Universal Rewrite Bureau Approved To Invalidate Orignal Notions; or for short M.A.S.T.U.R.B.A.T.I.O.N.
It seems fitting, since this is basically something being performed by certain individuals simply stroking their own 'egos', with the intention of just making themselves happy in the end, while vaguely fantasizing about approval by those they fail to please in real life. ^_^ And heck, a lot of male comic collectors will feel pretty at home in that universe.
