How about Cy Young award winners. There is a NY/NJ promoter who did multiple Cy Young shows and they were very successful. I don't know why they stopped. There are many winners who Cy collectors are looking for, like Dr. Mike Marshall, Rick Sutcliffe, Greg Maddux, Pat Hentgen, Barry Zito, Eric Gagne, Bartolo Colon, Chris Carpenter, Johann Santana, Brandon Webb and Roy Halladay. These are guys who are either retired or otherwise available for signings. There are many other big name winners who are still active like Kershaw, Dickey, Price, King Felix, Lincecum, Grenke, Lee, Peavy and Sabathia.
Female UFC fighters,Ronda Rousey,Meisha Tate,Paige Vanzant for example,or guys like Frankie Edgar,Cain Velazquez,some big name guys would be awesome adds for the April show.Also,more boxers,George Foreman,Lennox Lewis,guys like that!!!Keep up the good work!!!
