That really would undermine the OT in my opinion.

I don’t care. The OT will always be the OT; future films are going to up the anti in some departments so it seems like an excuse to not do grandiose things regardless of how good they are just because the OT was pretty simplistic in nature. If you can do more/better then why shouldn’t you? Should Stephen Curry not try to become the greatest offensive Basketball player of all time because it would “undermine” Kobe or Jordan? Of course not.

Also I don’t see how him waiting for Palpatine’s demise is a cowardly move, I’d call it tactical and patient.

He didn’t need to wage war with The Empire. He could have just killed Palpatine and assumed control over The Empire. He was at least an expert in the Dark Side at the time so I couldn’t see why he would take the easy way out. If Snoke were Plagueis you’d understand why he’s be more tactful after Palpatine’s assassination attempt.

I do think a new threat with it’s own new backstory would work better than to bring back some name that was given in passing four movies ago

Plagueis pretty much is a new threat. And if Snoke is Plagueis obviously his philosophies have evolved seeing as how he would have abandoned the Rule of Two so his end game could be completely different from what it was when Palpatine attempted to kill him. Furthermore, Snoke being a new character could backfire in so many ways if his back story isn’t written right. It’s the safer and better option (for the Saga at large) to just make him Plagueis.
