Yes, shorten both the bellhousing and mainshaft.
We do this to the G50s, and can do it to a "long" 930, too. $700.

You can dimple the torsion bar housing but only slightly. It's damn tough steel. We just did a G50 swap in a 1987 and it laughed at a 4# hand sledge and an air hammer. If it needs more than that, drill a small hole and see if yours is several layers of steel. It was in a 1976 we did, and we cut a hole in the outermost layer -- all the clearance we needed -- then hammered and welded the perimeter of the hole.

Otherwise I'd see about lowering both the gearbox and engine an even amount and using longer hardened bolts. We've done this for one-off builds. Justify it by telling yourself you're just lowering your car's center of gravity! :-)
