I'm late to this party, but facing a similar problem with a Parker GHE that is a beautiful gun, but that some boob installed a Morgan adjustable pad on. I'm pretty sure it will wind up with a 1-1/2" Silvers repro pad as the first solution. I hate pads, but I need more LOP on this gun and don't want to mess up the nice original wood and finish. If the gun were rougher or if the grade were higher, I'd consider finding a replacement stock or doing a butt transplant. I also have an Elsie Ideal that came to me with one of RMC's brother's hand-carved wooden butt plates, and he does excellent work. Not sure how I would feel about a similar solution if I needed 1-1/2", though.
For a Field Grade Elsie that's getting mostly refinished/restored, I think I'd go with the Silvers and see if I could live with it.
