Paloth, the answer to your question is YES :) Although I doubt that you'll want to do the weightmapping in DAZ|Studio, as it's a lot slower than doing the same thing in Poser Pro 2012.

I converted a figure from legacy rigging to weight maps in DAZ|Studio 4 Pro, and then exported a CR2, which then successfully loaded into Poser Pro 2012 completely as expected, so I can say with absolute certainty that it does work perfectly.
