I have made a prototype for reducing the overall length of the rear shock. To effectively reduce its length requires replacing the bottom clevis from the shock. To do this safely and easily, I built a shock compressor from some 1" thick plate aluminum and some threaded rods. This allows me to compress and hold the spring while removing the spring retaining washer. The threads on the shock piston rod are M14x1.0mm thread. I have the correct bottoming tap enroute. My test piece I machined from 1018 and 17-4PH stainless can be made even shorter.
I will make another unit from 17-4 for the entire unit including the pivot bushing, and showing the steps to accomplish this task including before and after measurements. When I was looking at the options for the front lower, you get some additional clearance, the bolts holding on the mounting clamps for the handlebars could be replaced with some longer units and add an additional spacer under the clamps. This will raise the bars up, allowing for the front forks to be raised farther upward in the triple tree. Pictures and additional information to follow.
