This mod was much easier than I had anticipated. About $16 in parts if you can find the pushfit adapters for cheap.
The only thing left is to figure out where to mount the original extruder body while I look into one of those compact MK8 style extruder style drives.
For anyone considering it, I think the LulzBot team’s choice to stick with the direct-drive geared extruder was definitely the best decision for consistency and ease of use. YMMV.
