Wouldn’t it make more sense Kylo was the scavenger, Rey was Han and Leia’s biological kid?

Least it actually fits their worldview? Like Kylo would be a dark sider in this hypothetical because he feels the New Republic did nothing to lift him from his poverty and also he could have some idolization with Anakin because of his background.

Whereas Rey would believe in second chances because she would have had Luke as a teacher. Plus someone mentioned she looks a lot like Padme.
