Checking around, the apps that do it for you suggest not to run them on 3.65. You could probably do it manually yourself, however, and it'd likely work.
However, I would highly advise against doing so until someone comes up with a way to safely reinstall 3.65 with Enso, purely as a precaution. While removing some system apps probably won't hurt anything for the most part, it's always possible something could be screwed with that could require a firmware reinstall, which currently means no more Enso.
