I can only point out from five years of experience buying and selling sheet music on eBay that the early Black caricature and minstrel music sells very well (second only to the classic rags) and purchased by the most serious collectors. And so I think there is an appreciation for the genre as American popular song history, and would expect that most collectors will never hear the music performed in its intended style.

One venue for performers might be exhibitions at the prolific ragtime or trad jazz festivals around the U.S. Trad jazz isn't that far removed from its roots that musicians and fans wouldn't appreciate and honor a recreation.
