I know this is old as fuck, but just noticing this. I would be interested to try it...
Also, on a somewhat related note, I am a huge fan of DND 5e and how streamlined it is. I've long thought of running a similar sort of "space-fantasy" game with 5e thats not grim-dark and more light-hearted. Spelljammer being a huge inspiration, as with old sword and sorcery novels. Some day....
