For me, while it's always fun to see new sets, I think if they just added to the current sets at times, with different chairs/props etc, that this would help. Also, if they'd change the lighting a bit here and there, just to add some change from the normal bright lighting (Not as bad as on Studio 66), that could be fun too!
They did the shadow play from behind the white sheets, with the nude women, and it was a fun moment that was short lived. I'd love to see that brought back, as well as a pool for some wet fun!
A few years ago, to me at least, Babestation had the best sets for a decent length of time, because they were coming up with inventive ideas. Many here seemed to dislike the Barbie doll set, but I thought it was ingenious, as it was something new. They shouldn't spend a fortune to try to impress us, but just a little bit of creativity that doesn't break the bank would be smarter.
I'm a broken record here, but I'm a big fan of atmosphere during sessions, especially the use of fog, dim lighting, strategic lighting, black lighting and so on. The steam during the shower sessions on these channels is also nice, and can add some of that tease factor back in, with the women using it in clever ways. Shower glass steams up, the women rub clear areas in the glass, giving a tease peek etc.
How about a two way mirror idea, where we could basically watch one woman on one channel, and also see through the glass to another woman on another set, getting different angles, almost like a voyeur style? Plexi glass frame, and nothing more, other than effective lighting and some decent performances!
