The issue is that I doubt it's going to work well in game. A lot of spells have hardcoded references in the emulator and client for doing different things. For example, opening a chest object uses a spell. Not to mention tons of spells have server side data or scripts outside the DBC that would need to be ported over.
It would be a massive amount of effort.
The better question is, why do you want to do this? There might be a better way to go about getting the end result you want.
