Manouvering hard during a go-around? Shouldn't happen or ATC didn't do its job in the first place. If something gets in the way it is a go around which on my tiny boeing means i will press the TOGA buttons upon which the autopilot will fly the go around path (both laterally and vertically) and the AT will produce enough thrust for a low climb rate of 1500 to 2000fpm or full climb thrust if i click the buttons a second time. If already flying manually the same is gonna happen, except that i will get flight director guidance only with the same thrust settings (we use the ARM feature, otherwise thrust would have to be set manually).
