Good points! Yes, I've often thought in these same terms as well. God incarnates Himself as the creator(to manifest is to incarnate, no?), then through His creative power incarnate the creation, then as a man who then becomes an offering for sin(this, too is a sort of incarnation as well, no?). He then ceases to exist altogether, or perhaps it isn't that he ceases to exist, but that he empties himself completely. What better way to illustrate this than with an empty tomb? What do we see then? Do we see the absence of his presence, or the presence of his absence? How much more reincarnated can one be that one's closest friends don't even recognize him?
I do think that the Christian view of reality takes reincarnation so much farther though. It takes it to a point where the incarnation is within God Himself and God is within the incarnation. The Father is in the Son, the Son is in us and we in him to the point that All is in all.
