Joe at muzzleloader emporium is working on just that. He and I have had long conversions, and I convinced him on the value of building a partial or full kit version of a heavy double. The prototype will be a replica of a Holland and Holland 8 bore he has. No dates on anything, as they have not figured out how to glue the barrels together yet.

I agree with you on the heavy duty parts, the Pedersoli locks on the 12 bore needed some work before they could handle anything over 130 grains. I sheared the left lock tumbler twice before I engineered the right sear shape/depth. The heavy recoil would slap the hammer back and slam the hammer back into the sear. Without enough depth and cup the sear pin slips and you get a double or failure. What would be better is a locking pin that would stop the hammer from traveling past the cocking sear. As I approach the magical 195 grain DG load, I'm relearning what the old gunsmith masters found out 160 years ago (such as the lock problem). So far the stock and barrel are holding up fine. I put 50+ painful 165 grn rounds through it today to test the new sear design, it held rock steady. I also was testing the trigger and lock tuning I did to it (I did the work BTW). The locks and triggers are ultra smooth now, which tightened the groups up (less movement when squeezing one off). I might strengthen the stock somehow, if it seems like it needs it. I figure I've put 300 rounds through this gun now, other than the left lock issue it’s held up. Side note I was having a lot of problems with ignition failure so I purchased TEMCO musket nipples however I can not find the caps anywhere locally. So, I decided Saturday to buy some TC Hotshot nipples to try. With these I had NO miss fires or hang fires at all today. They really work. Out of three 20-ball containers worth or shooting not a single miss fire. I didn't even squib any caps. I was using Mag CCI #11, but usually had 1 in 4-miss fires with them and the old nipples.

It was a good day, other than the major headache I gave myself with the heavy loads.
