Hey Vector,
As an avid World of Warcraft player myself, this project definitely sound interesting! I’ve always wondered myself how the game would look like given a new rendering engine.
Now, you might be interested to contact this person: https://youtu.be/qlNAJJtCfpI
He is working, a little bit like you, to “update” World of Warcraft to new graphics, fitting with the new next-gen era.
All in all, definitely something I’ll keep an eye at!
