This will be ignored. You're asking the current IW team (I believe the ones who made MW2 & the priors were re-assigned) to re-make a decent game. I think the only re-make that they could attempt and not fuck up, would be WaW since you can't have jumping suits, jetpacks and some dumbass guns when the time is clearly set to the World War era. Although, I am not sure whether the team at Treyarch are different or not.
I bet if they still had the old team at IW & Treyarch, with Activision on a "shut the fuck up and just publish the game" arrangement. Along with no other teams involved like Sledgehammer, we'd still be playing games like MW2.
It's just a shame that if the developers question the game, they get "re-assigned".
