Indeed, this is what Morrison-Knudson found out when they rebuilt a dozen RDCs to coaches for MBTA back in the 1980s. They had to completely redo the springing to account for the several thousand pounds of weight that were removed.^^Also, no doubt, towing lot of extra weight unless removed, then you get into the ride issue as previously mentioned.
But that step only needs to be done if you remove all of those devices as M-K did. Removing just the right-angle gearboxes and driveshafts is only a couple of hundred pounds, and wouldn't drastically change the overall weight of the cars.
