Protons inside, electrons outside. But why not the other way around? (self.science)

Every time I try to understand how forces which hold atoms and molecules together work, I find myself wanting to ask this question: why not the other way around? Could there be an atom which has electrons and neutrons inside, and protons outside?

It feels like a silly question, but is there something we know about the universe we live in that implies that this is not possible?

Thing is, trying to do a complete swap, there's a point when the thought experiment kinda eats itself: you end up with a universe which is exactly the same, except the words "proton" and "neutron" are swapped.

The logic of it is fascinating in itself.
