how hard would it be to mate the liquid cooled xr400 cyl onto the air cooled xr400 bottom end that fits right in

I have rode many XR400R's and none of them have been liquid cooled, oil cooler only. Exact same motor just different cam, carb and tranny.

Sandman, the cam adds more mid-range and top end without taking away hardly any off-idle power. It is probably the best all around cam you can get.
