Conquest-Sized TDM?

I feel like having a game type that was TDM on conquest sized maps would help prevent having snipers sitting in the back of conquest games not even attempting to play the objective. More of the less objective-focused players could just play that, because I love conquest but sometimes I don't feel like capping flags and working with my squad, but I feel bad doing that in conquest. I'd really like to see bigger maps so I could just snipe and not feel like a piece of shit, because TDM maps aren't big enough for that at the moment. Thoughts?
