Still looking, Couple meet play time.

Wife and I tried swinging, if you want. We don't swap, but it's our thing.about 5 years ago ,we we're with 3 other couples ,we just love watching an being watched ,same bed with other couples, along with some ** girl play while the husband's watch.then join in with our partners, yes the other guy can ** on my wife's ** with me as the girls play.then after about 3 years of doing this, my wife says she wants to stop , I ask why, she says it's because we can never really find a good match, one of the other wife or husband isn't her thing ,manly the husband, she had no attention to them.so I say ok what's the solution? She tells me she just wants to go out to bars an just let it happen naturally, if we find a couple that's OK with what we're into then we go from there.she doesn't want to make anymore profiles on sites.we had ours on SLS for 3 years. Problem is it's Very hard to find couples who are into it at a bar. So I'm looking to set up a meet at a bar, where it seems un planned an we meet a couple there for drinks an enjoy the night out. An have the other couple get things going , like the guys might go off to the bathroom or play some pool while the ladies talk, and have the other wife hint an ask if we've ever played with another couple to my wife, telling her how ** she is , and there looking to do some fun ** play an there really interested in us joining them. That would be the perfect way to let my wife enjoy herself without thinking it was set up. Might sound wrong not to let her know, But once again, this is how she said it would be better. Any advice how to get this to happen? Our any couple interested in meeting an having fun? With NO Expectations from either couple that anything will happen, NO PRESSURE. We're from south east Wisconsin.
