How to get nonstandard games going....

fwiw, "poker" twenty five years ago was Lowball, then it was 7 card Stud, then it was Hold'em. Around the Kitchen Table, it is usually 5 card draw. I am sure that another form of poker will be "poker" in the next few decades.

As for your question. I know that in California, you would be able to ask the floor if they would be willing to spread mixed games. I would start by asking the floor, and then informing other players about your idea.
