That would be a terrible idea. Young Avengers established that Kang is basically essential to the very proper existence of the MU timeline. When young Nathaniel tried to kill his older self, he caused a MASSIVE time paradox that fucked everything up. Wiccan and Hulkling were erased from existence, Jessica Jones lost her baby, etc.... Most of Avengers history was basically gone. So like it or not, Kang HAS to live and exist as Kang for things to be the way they're supposed to be.
