Replacing a flat buttplate with spurred

[Samuel S.]

I have a 20 ga VH (circa 1908 or thereabouts) with a spurred buttplate. It's beautiful, and the gun has been in my family for almost 100 years. I am purchasing a 16 ga. later era gun (1927) with a flat buttplate. Please don't shun me for this question: I am not attempting blasphemy, but would it be possible to inlet a spurred buttplate to replace the flat one (which is chipped, by the way)? I'm not concerned about what this will do to the value (please don't judge --- this will go to a great grandson some day, and continue its journey through the generations, if my wishes are fulfilled). Has anyone here fit a spurred plate to a gun that had a flat plate? I just love the spurred plate and am not a fan of the flat one. Any information would be helpful.
