i'm going to address this question two entirely different ways, so bear with me.
speaking in terms of quantum multiverses, anything that can happen probably does. i think it's safe to say with certainty that if a god could evolve, and this whole multiverse thing has any merit, that it has probably happened on at least one occasion.
also, in terms of the bible, the grammar of the sentance "god created man in his own image" supports this claim. one of the phrases in that verse suggests a continuing process, that we are evolving into god(s). jesus also spoke of the church as a bride for god. it's quite possible that the god of the bible is an evolved deity only responsible for creation is this specific universe, and that we are to be a companion for it.
of course, this is all crack-pot.
