Regarding points 1-4, that's exactly my own thinking. They may be nearly identical, but they're still somewhat different. Meanwhile don't even get me started on Eobard not even being referenced, lord.

The big potential problem that occurred to me in having "pre-Crisis" and "post-Crisis" is that the Crisis was still occurring when Earth-Prime was brought into existence and continued well after.
