Tailed Beasts Reincarnated Inside of Madara Uchiha!

let's say what if a few tailed beasts died in the founders era. i don't remember how the revival of a tailed beast works if a tailed beast dies or if a Jinchūriki dies - I refuse to go near boruto and I haven't rewatched some arcs of Naruto in a while (I do know Naruto dies if Kurama is ever extracted from him). But let's say the Sage of Six Paths Hagoromo realized how dire the situation really was. He needs to revive the tailed beasts via reincarnation. So, Hagoromo choose Madara Uchiha to become pregnant with the reincarnations of a few tailed beasts using Indra's chakra.
