Prolly isn't so I am doing it myself but it is a hassle so I wanna know if someone else had already done it or not.
Before people ask me. I want this cause I want less lagged in my game. Putting Pauldrons, Greaves, and/or Gauntlets together will do this. I've tested this on Bonemold armor first. Before hand, the game will lagged and the armor will be all glitchy like the Pauldrons are trying to overlap the cuirass and vice-versa. That sort of thing got annoying. After I combined the Cuirass, Pauldrons, and Gauntlets together; I didn't got none of this. Anyways, that is why I am looking for, or at least making, a mod that does this. Less lag and glitches. (This is something I agree with that Bethesda did in Oblivion and Skyrim)
