Hey, I'm new here, but what a great idea for a figure, Luke. Am I correct in assuming that, in addition to being similar to a RH star sans hands, that the dancers are also facing the same direction throughout the figure, like you're supposed to do for a regular two-person do-si-do? So the dancers would be walking forward 4 steps, moving around three other dancers, and then reversing back to place? I can't see it taking much more time than a regular RH star. The dancer's adjust, just like they do to any other figure that takes more or less time than allotted, realistically. 

There's also a figure from English country dancing, which is not much like you're suggesting, but it may provide some inspiration for tweaking this figure. It's called a Mad Robin and involves 4 people doing a sideways do-si-do in couples. 

What if you had the closer women do a do-si-do followed very quickly by the next two? And then take the previous suggestion about choreographing a "soft" figure afterwards, so the one or two beats is not an interruption.
