The Ultimatrix does not record the Ultimates' DNA. Instead, it evolves them each time the evolutionary function is used.

Anyway, I'm pretty sure Ultimate Alien X is impossible. Not because they are omnipotent, but because of their life cycles. If they (Celestialsapiens) can't reproduce quickly enough to pass on evolutionary changes, they will die off.
