Anything is possible given enough time and money Frank. Whether it's worth doing is another thing completely.
It would mean constructing a fixing point for the suspension cantilever and making sure that it was in the right position to give you the benefits of the rising rate stuff....and I have absolutely no idea of the geometry at work there. A lot of work to get right first time. You would also need the suspension rocker (or whatever it's called) and the tie bar etc etc...
Ultimately, I've ridden both bikes and couldn't honestly feel any major difference in either type of rear suspension set up.
