Sharps percussion to metallic cartridge

[last]

Hi there, I'm curios if it was possible to replace the breech block on a percussion sharps with the block of a 45/70 sharps.

Would a pedersoli 1874 .45 sporting sharps' block fit in a pedersoli 1863 sporting sharps?

I guess you would need to change the hammer and perhaps reaming the chamber too?

Anyone tried something like this?

You can swap out the breech block and hammer with no problems but I don't know what the chamber dimensions are for the Pedersoli. You may have to ream it or you may have to sleeve it. You will also have to have it cut for the extractor.
