I don't think so: it will oblige makers to standardize processes and software across phones... i.e. very basic specific drivers, then same OS and libs on all phones (with just different themes).
Then the Android security updates can be uploaded directly from Google at no cost. Just like for computers, and phones are computers with very few different features (input device, GSM chip).
My HP or Dell computer is not more expensive when Microsoft or Debian is pushing security updates.
In the end, unifying processes and software brings costs down.
