There’s no porting of files from Oblivion to Skyrim. Everything is made/remade from scratch. That means there’s no copyright violation to enforce.
Plus they’re taking one Bethesda game and bringing it into another Bethesda game. And Bethesda already had 1.5 years to sell the official remaster, so this can’t really hurt sales. And trying to C&D a community project they’ve been aware of the entire time would kill any goodwill the community has for them.
So no, it’s highly unlikely to get a C&S. Bethesda isn’t Nintendo
Odds of this getting C&D’d?
Essentially zero. Bethesda has indicated that they’re aware and supportive multiple times.
They even invited the creators of this mod after the release of the official Oblivion remaster:

If you make enough noise and get the community mad enough they kinda back doen just make sure you arent essentially letting people “pirate” the game.
There was a Bethesda lawyer in the forums for openMW many years ago who they managed to work with and not get the project taken down.
