Didn't Goodman Games release an rpg called Eldritch? I don't have it but it didn't seem to make much of a splash.
Beat me to it.
Honestly, I think people who want rules light system need to find a rules light system and convert the adventures that they want to play instead of trying to shoe horn D&D 3.5 or Pathfinder into a rules light shoe.
