Nope it would be neither lame or stupid

each of them have half of the sages power and both need a power boost to actually defeat Kaguya. the only place to go is up and the only power boost that would give them the chance of beating her is if they both gained the Rinnegan

also since Black Zetsu said that both uchiha and senju can awaken the Rinnegan then the obvious conclusion is that if both get a power boost it will be the Rinnegan the only other way for them to compete with her is if sasuke gained the Rinnegan in both eyes and Naruto gained the Byakugan but since he is not a dependent of Hurama he can not gain the Byakugan unless he steals a hyuga's eyes(which he will not do) so the only other option is he gets the Rinnegan as well
