This thread prompted me to re-watch "Tombstone"
In Kurt Russell's western revisionist view of things, Fly's Photo Studio sure get shot up a bit at the OK Corral. There is also a scene of Earp's love interest having a boudoir photograph taken by Fly!
So I guess the filmakers certainly heard of him.
PS, if you are going to take up a rephotographic project of old western photographs, you might need to get one of those Sam Elliott type moustaches though...
