No, we need an alternative smartphone ecosystem like a hole in the head. Android won, and AOSP is free software. There is no reason to undertake the Herculean task of writing a new mobile userspace core. You might as well write a new kernel while you're at it. What would be the point? What are you going to do better than AOSP? A 5% more efficient binder?

At Google HQ, there is a veritable mountain of skulls of Android competitor projects. Please notice the skulls before doing something that will almost certainly add your project to the pile.
