I'm with rifleman 1776, above. Sounds like you want a shooter more than something historically based. As stated above, 36" is shorter than any known examples of original fullstock "poor-boy" or "Tennessee" rifles. The current offerings of these rifles and kits by TVM, Track of the Wolf, and many others are based off of 1970's re-creations that were made to suit folks coming over to black powder from the cartridge side of things. Original late flint/early percussion iron mounted "Southern mountain rifles" usually weighed 9-12 pounds, had huge thick barrels with small caliber bores, had hand-forged hardware of great variety, and distinctive styling from region to region and maker to maker. Then in the 1970's Herschel House and others started making their own styles of iron mounted rifles based loosely on originals. Those guns are now called "Woodbury" school rifles. If you're primarily wanting a light weight squirrel gun for hunting, your plans sound fine, and it won't matter whether it's walnut or maple, choose what you like best.
