Amazon is already doing something similar with the Kindle Fire. It uses Android as a base but with their own separate development path; a fork. It means that they can do whatever they want with the code, but they're basically on their own.
I think Google blocks Play Store access from forked versions since it could create compatibility issues, but I assume also to discourage forked versions as they move away from Google's ecosystem. Amazon have their own app store with it's own publishing and licensing system. So more work for Android developers who already have to worry about tons of phones with different hardware configurations.
