55 year old Batman, with over a decade of prep time and full knowledge of the Norrin and what he can do, takes on the Silver Surfer in the Heart of Gotham City...
Batman is attempting to simutaneously fake his death and teach Surfer a lesson...
Ten years?
Its possible.
Doom's a prep peer of Batman's, and managed to steal Surfer's power. Thats a type of depowering.
I'd lay odds on Batman being able to pull off some similar feat, even if he didnt want/manage to score a power up out of it.
Not sure there are any. Like "speedblitz" posts, "Batman-with-prep" got overused, cuz its highly subjective and unquantifiable nature often rendered debate moot.
Perhaps couch them in colorful metaphors

The problem with prep battles is that they're very vague. I could just say "oh well Batman just make a device to drain Surfer of his powers" but that's vague as hell.
Batman with 10 years of prep could solo the Multiverse
Batman would simply construct the hell bat suit, which allows him to be on Abstract levels of power (He survived a fight with Darkseid who is a high end abstract level being).
Batman is in no way a prep peer of Doom. Not even close. I don't see him being able to do this.

He doesn't have to be, this isn't some high end prep battle to beat some abstract level character, it's 10 years to beat a high end herald level character, 10 years of surveillance, studying the power cosmic, studying Surfer's behavioral patterns.
Hell 1 year or several months would probably be enough, 10 years is overkill
To add, while the ambigous "prep" scenario makes me not exactly have a clear idea on whether or not batman wins, the whole "drain the Surfer" scenario might not be feasible anymore.
As current Surfer has resisted being depowered by Galactus himself by simply temporarily "de-silvering" himself. And he did this just as Galactus blasted him at point blank range.
