Some of you may know of THUGPro, a mod of the PC version of Tony Hawk's Underground, which aims to overhaul the game to a state of near perfection, partially by phasing in elements from the Tony Hawk's Pro Skater (THPS) series. At least that's what it seems to be from what little research I did

So I had a thought: would it be possible to make something similar on MW3? Could MW3's Steam release be overhauled and made as pro as it's perks?

This is where my knowledge ends - I simply don't know enough to answer this question. So, Call of Duty experts, answer me this: can MW3 be fully modded like THUGPro?

Bonus question: when the Black Ops 3 mod tools are finally released, can this be done to BO3?
Secondary Bonus Question: what about W@W?
