[40K/DC] Superman lands on Holy Terra

So, instead of landing in smallville, Kansas. SSuperman's craft lands on Holy Terra in the Dark age of technology, how does this affect events leading up to the 41st millennium?

In all likelihood, he'd have been taken in by the Emperor and used as part of the geneseed for the Primarchs assuming he found out about him. Otherwise, you just have normal Superman in Grimdarksville.
