From dkingsjr: So I don’t have to be a PADI OW diver to get any further PADI certificates?

Absolutely not.
Your NASE OW cert meets all the prerequisites to enroll in PADI AOW if that is what you choose to do. You could also continue with NASE AOW then go to PADI Rescue if you wanted. The only time your agency choices become an issue is if you want to obtain either PADI Master Scuba Diver or go the professional route. In that case, you should start taking classes with PADI (for MSD) or whatever agency you eventually plan on going pro with.

As long as you are not going pro or the PADI MSD route you can have all your certs with different agencies.

I am curious why you feel the need to "switch." Knowing that would help me give you a better answer.

I am an instructor for both PADI & NASE.
