You may want to cherry-pick instead.

For tracking purposes, if you do cherry-pick, could you use the -x
option.  Could you also be sure also modify the commit message to note
which git repo it was cherry-picked from, eg:

(cherry-picked from <sha1> git://

In the event that the patch does not cherry-pick cleanly, could you
modify the commit message to note it's a backport rather than a clean
cherry-pick, eg:

(backported from <sha1> git://

Sounds fine.
