I would suggest an alternate approach. If you can find one second hand, take it apart and refinish it. There is a lot of extra wood on the stock (for instance, the forestock doesn't blend into the barrel, but has flats that run all the way down, and the lock panel can be sharper). Remove the blue or brown, and age the barrel using blueing that you wipe on and wipe off, just graying the barrel (browning was less common than blued or bright barrels in the early 19th century - much of the browning we see on antiques is actually patina, or age). You might be able to save a buck over the new kit price, and can put a good deal of "you" into it as you refine the wood and finish the wood and metal. Just a suggestion....I have one in .45 that was given to me, and my plan for a winter project is to work the wood down a bit, refinish, etc. for my son. I might have to shoot it some, too....
You might swap out the rear sight too, to something more simple. Pedersoli long rifle barrels also often use a "patent breech", meaning there is a smaller chamber within the face of the breech plug, instead of the old style where the builder would simply drill the touch hole just in front of the face of the breech plug. So you may need in a .32..., a .22 caliber, pistol brush, to get into that chamber and get the crud out.
