I do not think you will see any iPhone product 'forks' with a subset of the current OS. The iPod series save for the Touch is not iOS. iOS is about driving capabilities to mobile apps. A 'nano' phone would cause both OS and Apps to 'fork' their code, and mix their message.
Apple will not create a iOS 'consumer' 'pro' and 'enterprise' version of the phone in a forward motion (ala Microsoft). It's about increasing capability for same $$, not cutting existing capabilities to hit a new price point.
But that's the thing...I wouldn't characterize it as any kind of iOS fork. iPod nano is not iOS in any way. It has the veneer of iOS-ness, that's it. They did this to bring iOS mojo to iPod nano without actually cramming iOS into that device. I'm suggesting the same possibility for an possible iPhone nano.
If only it were that simple and easy. Sadly* these other companies also think about profits, not just revenue. Were it as easy as you suggest, it would have been done.
*Sadly for your theory, but happily because unprofitable companies have a nasty habit of going away fairly quickly.
