For the last few years I played in a band with a standard 25.5" scale guitar tuned to baritone tuning. Not quite the same thing and the purpose behind it was to play very heavy heavy metal, so it's probably not what you're looking for
Anyway, a non-metal loving friend of mine who had an interest in getting a baritione played it and was dismayed, not that it was hard to play or sounded bad or anything like that, just that he had a hard time getting his head around the tuning and how he would use it in a more normal form of music, so try before you buy, is the message there, I suppose.
