Technical HD Graphic with old models? Like Classic

[Drunkuser]

So while watching some classic videos, I noticed what it seems like a better, cleaner, hd graphic, with new water, but with the old models.

Since I'm not a fan of WoD models but would love to improve everything else, is there a way/patch to import this on my folder for warmane wotlk?

Is there a way? Probably.
Is it recommended? Probably not.
Custom patches have a way of causing crashes, lags, odd behaviour and may be picked up by anti-cheat as client side modifications in the most extreme cases. New water is probably more than just a simple texture/model update so that's very unlikely.
