Spontaneous meet up

So me and my wife have been dabbling in the lifestyle for a couple years but only to the extent of going to the swinger club and being watched and messing around with each other in the group room we both want to take the next step but the club seems kinda cliquey so I was thinking of setting something up at a local bar and we would “casually” run into a couple and they just “happen” to be swingers is that a bad idea to not tell the wife that’s the plan but completely include the other couple or single party?
