Lucas will have average options. 

He is sculpted with an athletic build primarily to help define muscle groups for topology, rigging and weight mapping. His topology will not adversely affect morphing, I'll make sure of it. (Unless you're trying to make dragons and unicorns - if that's the case, go play with genesis). He will be stretched pulled and twisted into every conceivable position and (human male) shape possible before he's complete, to make sure that he handles morphing and bending well. 

I think that some of the biggest reasons few people use the poser-native figures is due to their topology and flaws, that make it difficult for content creators to make new content for them. As I recall, P6 James, for example, has really bad UV mapping, making it pretty near impossible for him to be retextured without having a program like ZB that can paint 3D models in real time. I think someone was trying to correct that at one point, but I don't know if it ever happened, or got distributed. 

Thing is, P6 James and Jessie are actually the most anatomically accurate models of all of them. If it weren't for their underlying issues, I think they would have seen a lot more attention from content artists.
