I have been working on some reasonably simple rules for a pod racing game based on some of X-Wing's game mechanics and the first version of the rules are now available on BGG: https://boardgamegeek.com/filepage/116069/pod-racing-x-wing-style
Suitable miniatures are still available if you know where to look and can be made compatible with the X-Wing bases:
I would be happy to answer any reasonable questions about it here. The game is still at the play-testing stage and I would be interested in hearing what people have to say about the rules or concept.
Cheers!
