It's a shame nobody has managed to get a release on something like this since 1.3.1, but it's worth a try and get at the very least the tools to do this working seeing as KSP 1 won't be changing all that much from here on out.
Karbon would be a good one for trying to get a revival project going, as it wasn't too ambitious but I can't find a dev threat on it sadly. Will still try and get something going regardless. Thanks for the help on this, I'll update this thread if I end up getting the ball rolling on something.
