It can be done....I've seen it done, but there will have to be some modification to the gearbox mounting.  This is completely different and will likely require some welding/fabrication.

It may technically be possible if you really wanted to do it but it would be a massive jobs as the plunger engine is semi unit, the gearbox bolts to the back of the crankcases whereas the swinging arm engine is totally separate from the the engine. The length of the engine + gearbox on the plunger is much shorter than on the swinging arm model so there may be issues with squeezing it into the frame.
