The problem with this is that Edo Tensei needs DNA to bind the soul, and Hagoromo called back actual souls, without needing any body to bind them in and no DNA to identify the soul. similar to how Lady Chiyo could bring the dead back, but a Rinnegan User needs no body.

However, Nagato had his rinnegan for decades and still couldn't use Limbo. If he could, he would have.

Obito had Rinnegan for a few weeks at best, so saying Nagato's proficiency was because he's an Uzumaki is a weak argument. Especially since Obito was an Uchiha (Sage's eyes) AND had hashirama's cells (Sage's body) and logically should've been able to use the Rinnegan much better than Nagato. But like i said, Obito only had it for a short while.
