I admire your self-reliance, your progress in gunsmithing and collecting antiques, as well as your acumen to build up a business from this hobby.
BUT Nah. Stagnation makes us Grumpy old men - just ask the 3 grandkids living with me! Fresh new ideas led to the Un-Mentionanables systems now in use and the "progressive'" implementation of in-line hunting arms. Been there and done that too; However, now I'm once again back to external ignition systems (stagnating away) where one can putter with old ideas and experiment with cantankerous hardware to coax out the best performance. Oh, I've got some nice antique arms - but I am conservative so they are all locked up and they don't see live firing, ever. Then there's the repros and hand built stuff that gets toted out into the woods and used up!
Bottom line: Maybe, just maybe, we should all simply enjoy the pleasure of burning black powder in front- loading firearms and strive to let our BP brothers live-and-let-live for our time remaining here on Earth's sod.
