I don't think so.  You're basically building a sheath around the original object.  With Auto Topo, you can define the polygon flow using projected splines.  It's fairly neat.  However, I haven't had the program for too long so I can't claim to be an expert on it.

Yeah, the overall advantage in Poser would be retaining the UVs, the morphs and so forth.  I have faith that the feature set for the game dev will be improved.  Dropping a bug report (I think its possible via web form) would help expedite features folks would like to see (that's not directed to you, just a general thing).

Another thought for ZBrush.  Since the decimation is superior and you have several choices via plugins, does it support FBX?  One could go that route if so.  FBX out of Poser, use Zbrush decimation?
