Erm. There isn't real support for this. Reasons 1-3 are just reasons it's possible, not reasons it's likely. Also, Flowey can't teleport, just tunnel, so he couldn't take the boat with him without severely hampering his speed. And, to quote Cryptonomicon, you only need one counterexample to disprove the theory. During Asriel's short midterm of having no SOULs but not being a flower, your theory provides no explanation, yet the River Person remains.
