Not aware of anything specifically for that rifle.
But, if you were to contact Richard Beauchamp he might be able to line up a breech plug for it and whatever else it would take to hang it into place. Then get a barrel from which ever barrel maker you like in the size and caliber you are after then have a gunsmith cut it to length and tap the barrel for whatever size threads Pedersoli uses, put it all together and viola, there you are. Not as easy as a drop in, but an effective work around.
Have fun with the project.
