help needed: mdd 2.0/mochi ashi compatibility? +other questions

Hello all! I have a big favor to ask of anyone who has both a MDD 2.0 and MDD Mochi Ashi. I want to know if it would be possible to put the legs of a Mochi Ashi onto the 2.0 body! I'm not sure if the frames are compatible or if the pieces would look odd together or anything like that, so if someone could test it (or knows right off that they would/would not fit), please help me out! (other request: if anyone could show me what a ddh-19 looks like on a MDD 2.0, that'd be wonderful!)

Seconded, I also would be interested in the parts compatibility between the f3 and the 2.0 bodies, especially for the busts and thighs' outer shells! I wonder how much the bodies and frames can be hybridized.
