Thanks for all the advice folks! I've been looking around for awhile now but haven't been getting very far very fast. I will keep looking.
As for a design opinion....I think that most people fall in love with a dulcimer for the captivating sound and as long as it had that "sound" wouldn't care too much what it looked like unless they performed with a traditional group and wanted a traditional look. You can find just about any kind of music being played on HDs these days. Your aerodynamic design sounds kinda futuristic. I bet there'd be a niche for it somewhere, Catspaw. You'll have to make a couple and report back on how they sell.
Thanks again, all.
