There was a thread on it somewhere. There have been surprisingly a good amount of cross-breeds (unnatural of course). Theres angsorii-endli, endli-lap, ornate-endli, palmas poll-senegal, and a couple others as well that I can't remember off the top of my head. I also remember once seeing what IMO was a delhezi-senegal hybrid and posted a thread on it on here, but I don't recall it getting much interest.
