Wait, you're arguing that it's a dimension accessed through her Rinnesharingan. Okay, so since the Rinnegan and Sharingan came from the Rinnesharingan, that means it makes sense for Sasuke to be able to summon/ open portals through here and it makes sense that Obito can open portals in it with Kamui.

That still means it doesn't make sense for a Rinnegan user to summon in or out of Kamui.

Also, using Obito's naivety? At this point he was heavily trained by Madara and could physically contend with Minato, and he killed dozens of Jonin/Anbu of the Blood Mist Village immediately upon awakening the Mangekyo at all. Obit knows how Minato's FTG works, and apparently knew that if he got him to Kamui's dimension it'd be over.

There's literally nothing pointing to anything being able to summon a Pain out of Kamui's dimension. There's more evidence that summoning out of there is impossible for anyone without Kamui
