No it wouldn't. They weren't trapped in the same dimension. Mallus seems to not just be someone who recently fell in from magic to science. He knows his stuff. The philosopher's stone may look like a magical object, but it is scientific. He is Barry and he is not exactly a magic guy. Only thing magic about him is the facade he gave that he did dabble in the mystic arts. Also those different voices were only the voices of those he caused hallucinations of. Mallus didn't use Sara's voice when talking through her. Nor Nora Darhk. Lets face it, this is just a case of CW having some similarities between characters. They do this often.
