Not for this submission, no.  However, I'd still encourage you to
proceed with the legal paperwork, so that you could contribute in the
future.  Thanks.

I pushed the new input method to the emacs-25 branch.  Please take a
look at the final result, because I needed to make a few changes
before it compiled successfully.
