What you describe is really close to the "multiverse interpretation" of quantum mechanics. It is an interesting thought exercise, but it is really important to acknowledge that it is only an interpretation, mathematically equivalent to the other ones, and experimentally unconfirmable.

As to Penrose's ideas on consciousness, they are many other problems with them (see Wikipedia for a quick list of sources; or Scott Aaronson's lecture notes).
