Jason Nelson is the publisher at Legendary Games. Yes, they're a 3PP, and to be honest, their stuff is awesome. I believe he's been asked about HL files previously, but I can't remember what the answer was, other than that it was broadly speaking negative (not that he has anything against HL or LWD, just the skillset to convert their work isn't present in the Legendary Games crew). I do think they would leap at the chance to get their work available, though, they're just not going to be able to do it in-house.
