Ideas for Appalachian barn gun

Kind of a long story, but I've been working on a number of gun projects in my shop over the last 4 or 5 years and have really lost motivation (plus gotten involved in a lot of other projects) and found myself unable to finish those projects. I have a friend who builds part-time, commercially and he agreed to a deal whereby he'll complete my projects and I'd give him most of the remaining stock wood and project wood that I had in the shop (he drove away with a full Toyota Tacoma bed full of stock blanks and various other curly maple, walnut, cherry, curly ash and even a piece of zebrawood). I also gave him a really nice set of micro carving chisels and tools and a few various other items. He's happy with the deal (says that he easily got the better part of the deal) and so am I because frankly I realize that I wasn't going to work on or finish those project guns anytime soon.

So, one of the six guns that he'll be completing is a Rice southern classic barrel, an English style lock (I think an L&R classic) and a blank of wormy American chestnut. I initially had the barrel bedded by Mark Wheland, inlet the tang/breech myself and drew a Rupp profile on the stock before realizing that A) I don't really care for the Rupp style and B) I don't know that a Chestnut stock would be fitting for that style of rifle. What I do think might be more historically correct and more appealing to me would be more of a generic Appalachian style barn gun, either with iron/steel furniture or perhaps done in a poor boy style with antler on the top of the butt (no actual buttplate though), a bone/antler toe plate and either a poured pewter nose cap or possibly a cap made of horn (I gave him a couple of horns, several antlers and even a few pieces of mammoth ivory too).

I've done a search and have found a few examples, but many/most of those were more of a Carolina style southern gun and I really want more of a generic PA/VA style maybe. Can anyone point me in the right direction of a resource for plans or pictures or does anyone have guns that they've built in a similar style that they'd share photos of? For what it's worth, if the English style lock won't/doesn't work for this style very well, I could also have him substitute for some brass furniture and a small Siler lock that I sent with him too, but was planning to use that stuff on a Lancaster gun that's in the lot. Really interested in thoughts or photos that anyone might be willing to share.

For what it's worth, the .50 southern classic barrel is pretty light and I'd think that the chestnut stock is probably a good bit less dense/heavy than the average maple stock as well, so what I envision is a nice, light rifle that I could throw a sling on and still hunt all day with without getting worn out carrying something heavy.
