Certainly would :) Also I've studied COREMU: 
http://ppi.fudan.edu.cn/_media/publications%3Bcoremu-ppopp11.pdf
But they are based on v0.14 as I can remember and seems that this 
project is not going to come upstream.
Anyway, thee are a lot of useful approaches they done while facing 
different problems on the way of paralleling the TCG.
I'm sure that those approaches should be used in future work.
