I could write a very long answer to this one, but I will limit myself to two changes.
First would be to ditch the Sitka, (you knew I'd say that didn't you Steve

). Great when driven hard but I feel sitka topped guitars can lack a little in subtlety for most fingerstyles. Ideally put a good Euro top on it or for a warmer sound a WRC or redwood. Englemann could be an alternative.
Second go "parabolic" on the braces, top and back, this gives more attack and better separation, in my opinion, which is what you are after for fingerstyle. You've already got the mahogany B&S so you're already a good way there in terms of lack of muddiness that some rosewoods seem to impart.
However, a major caveat to anything that anyone might say. What style of fingerstyle are you talking about? you'd really need different guitars for Travis picking, or for delta blues, or for modern contemporary and percussive styles.
Maybe you should change the 14 fretter to a 12, to move the bridge back to the sweet spot?
Not a simple question is it?
