It would certainly make more sense than the hideous and completely pointless 5C. The 5C expensive as it was, was constantly said to be the budget iPhone (albeit not by Apple), and quite frankly people didn't want to be seen as the person who couldn't quite afford an iPhone 5S. They know they could say that they preferred the 5C and the funky colour or whatever else, but they know that people are still thinking they couldn't quite afford the 5S.
Different size screens however are a different kettle of fish. With the same kind of body, I would go for a 4.5" or 4.7" screen over a 5" screen even if it was the cheaper model simply because for me 5" is too big (you don't often hear that phrase outside of phones) so I think both models would sell equally well.
