It sounds logical, but souls aren't genetics. I know Tsunade's a grandkid but she has almost nothing that you can pin down as being Senju. Her regeneration, etc stem from a seal and chakra control. And that's someone from a two-clan bloodline.

Until Naruto dies, Ashura's chakra ain't going nowhere (or he could perform some highly questionable experiments on Boruto, there's that). Boruto will get his regular Uzumaki side, though Kishimoto apparently no longer cares that they're meant to be known for their fuuinjutsu. It would have been nice to see Boruto using the Adamantine Chains or some innovative sealwork instead of Chidori/Rasengan/whatever.
