Deere 959K, hotsaw to processor. Feasable?

In order to reduce our outside costs and streamline our productivity I am considering putting a waratah 624 on a John Deere 959k buncher. We would like to put the buncher head back on when it is needed to cut a unit and then put the processing head back on to process under the yarder. What all would need to be done aside from the obvious hanging brackets and piping on the Boom?
