I don't see a lot of pieces with both Threeleaper and Tripper moves; I think the Cheetah, the Sabertooth, and your Troll are about it. And after looking up the calugo, I think that's a perfect name for the WGH regardless of what anyone else calls it -- though of course, it needs a good FGH to go with it. (I'd recommend the Draco.)
