Star Frontiers Without Number: a conversion

Reason for doing a conversion: at its core SWON is a D20 system and since D20 based RPGs remain the 900 pound gorilla in the RPG market it makes sence to open up Star Frontiers to a segment of the hobby that only knows D20. Plus SWON is a rather elegant presentation of D20 rules IMO. Secondly you can create any human SF character with SWON as is so why not adapt it to the SF setting and open up possibilities for dralsites, vrusk and yazirians in this system? There is also the interesting correlation of only 6 levels of skill in SWON which could aid in converting characters.
