There won't be anyone in position to answer this, as it is a new scheme and no one has been thru this so far.
All that can be said is that it is legally possible. Be aware however that if you can't show some PIC time you're going to be issued a CPL by the CAAC after you have passed the CAAC check ride, and will have to go for another CAAC Sim check during your upgrade process. The fail rate of these checks isn't exactly zero...
