Create it from upstream? Yep! Try this:

git checkout -b 3.7 upstream/3.7
git push -u origin 3.7

That'll probably have to chug-chug-chug to push all that content up to
GitHub; AFAIK they don't have any optimization for "this commit
already exists in another fork of this repository", so you'll have to
upload everything as if it's completely new. But other than that, it
should be quick and easy.
