I don't think it's easier, I think both could be implemented with
similar efforts, and in the same place in the code.  (Caveat: I only
thought a little bit about the implementation, so I might be missing
some important details.)

If you don't have a copyright assignment for contributing to Emacs,
you should start the legal paperwork rolling, so that it's in place by
the time you will have code to contribute.
