Factory conversions of ejectors were done often. The work to the actual frame is minimal. It includes just drilling out the trip pin holes, installing the new plungers and swapping out the roll joint.
Most of the work would be in the barrel conversion. I wonder if Parker would have converted the rib extension, or changed it out...
I would wager converting since changing out would require removing, re-soldering ant matting it.
