They were pretty tolerant of Gargoyles fandom in the past. It would be a P.R. black eye if they suddenly got draconian on this one. (It would be like if they went after every person wearing a homemade Marvel Superhero costume at a con.) They want our money after all.

Since there has been a trickle of H.S. merchandise over the years, finally releasing the damn thing (with a retrospective in which everyone involved has a good laugh) would be the next step. I fear some music licensing issues might come into play though.
