I've read the northern & southern parts are so different, they might as well be different stats. So, WI they were? What would it take to achieve? Could the eastern & western borders be different? (The OTL ones leave me thinking they wouldn't make viable states.)
Does this inevitably lead to conflict with Spain (or Mexico) at encroaching their borders?
