Other practical problems with converting/selling this Galax dulcimer into a baritone: First, people looking for a baritone mountain dulcimer usually don't want wooden tuning pegs . Also, most people looking for a baritone dulcimer will be chord style players , and this Galax is a real traditional wooden pegged dulcimer with no 6.5 fret. It's daunting to play a diatonically fretted dulcimer in chord style without a 6.5 fret. Baritone players are not going to want to retune in order to play various tunes. They want to stick with standard baritone tunings. And to play chord style in typical baritone tuning means you'll need that 6.5 fret.
Though not a precious museum antique, this is nonetheless a lovely traditional vintage Galax dulcimer (and such beautiful naturally blonde wood! ) though it seems to lack a double back. There is a substantial market for traditional Galaxes. It would be a bit odd to market this as a "Galax Baritone" since Galax dulcimers weren't made as baritones. There is also a good market for baritone dulcimers, but most folks who know dulcimers and are looking for a baritone dulcimer will avoid a wood peg dulcimer without a 6.5 fret that is obviously a Galax dulcimer. They'd want a more modern large scale dulcimer with 6.5 and 13.5 frets, and geared tuners.
And if for no other reason... I'm pretty sure you would get a better price selling this as a traditional restored Galax and not a concocted Barilax. (sounds like a Barium enema, hahah). If someone who loves vintage instruments did buy it, they'd probably immediately turn it back to a traditional Galax stringing anyway. Why not bring out its own natural beauty and appeal in what it is? Just my two cents.
Do take another look at the gorgeous droolyworthy Galaxes shown on Ben Seymour's site. They are so wonderful! I'm extremely lucky to have a custom Galax made by Ben. But this Delser has heaps and heaps of charm, especially if you let the beauty of that blonde chestnutty-poplary wood come through. 
Those look nice and bright, fresh.
