Even if it turns-out to be technically feasible, I wouldn't bet my car on this ever happening.

Think of it: Daz Studio (with its clumsy UI) augmented with the features of Carrara, Bryce and Hexagon, as outdated as they may be, could take the industry by storm, especially if it's offered for free.

So why isn't Daz doing it? The short answer is: If the folks at Daz could do it, they would have done it a long time ago already.
