If I were extending the LOP on those guns I think Leather covered pads would be the way I'd consider first. I'd also give them a light refurbishing by someone like Perodeau or Merrington. Then I would shoot RST or Polywad 2 1/2" cartridges in the all day until my shoulder was sore.....and that'd be a long time. Congratulations on a beautiful pair reunited! I'd love to know more about the good General/Colonel who originally purchased them. Maybe he gave himself a promotion present with #2.
