Ah, but if you make changes to the android userspace that aren't accepted upstream by the core android development team, you'll be forking the android userspace. And given that they are continuing to add new features to the android userspace, what makes you so sure that the handset manufacturers will follow *your* tree?
Note also that the handset manufacturers also don't want to reveal choices they may have made vis-a-vis to-be-released hardware until the product is ready to ship. Hence they make their changes in private trees that only get shared with partners (including the upstream Android userspace developers at Google as well as their chip suppliers) when an NDA is signed.
So it's not clear they will be that interested in using a baseline from a newer kernel version. Especially if the changes you propose making to your forked version of the Android userspace don't contain the latest and greatest user-visible features....
