Getting the Smokepole bug

Seeing some projects here folks are firing up I sort of catching the bug myself.
Keeping with my Military History collection I was looking at building a Brown Bess of a Kentucky rifle to represent the Revolutionary War.
I want a Kit gun but I also want to be able to customize the components I use.
As example I would upgrade the stock to a really nice crotch grained walnut.
Problem I am finding or I am missing the place to look is that there are no customizable kit guns out there.
All I can find is Traditions Kits and a few Lyman Hunter grade type kit guns.

Am I just missing the places I should go?
Navy Arms you could do just that but they apparently are no more.
