The only thing I said was that if there are maps animated through the nif, then you can't change them through BPCore (animated or otherwise).
How or what you do is for yourself.
About the Nemesis Sovereign Bridge upgrade, I'm not sure, if it's the stock Sovereign Bridge upgrade, then it has BPCore animated maps (or rather, a mix between the 2, BPCore for the new parts, nif animations for the old).
As a rule, you could say that any map referenced in the bridge plugin can be animated. And, don't forget, there are more maps than those mentioned.
