As someone who uses a Note 3 for personal and an iPhone 4S for work I can say I would not want a 5.5" iPhone, I have been waiting for a 4.7-4.9" iphone at most. If they "premium" the 5.5" phone they will simply tick off customers big time which is par for Apple anyways. Rumors of two launches months apart is copying Samsung with their multiple Galaxy S launches, and making people wait and regret the one they got instead of the one they wanted. Apple has been smart at offering all sizes and colors on day 1 which makes a great move, offering different screen sizes, colors and storage or premium on the bigger model 2 months later will alienate customers.
