Check out the Phottix Stratos 2, they allow grouping and might be just what you are looking for. I'm extremely happy with those triggers.
I just ordered a bunch of stuff from Phottix and I'm extremely impressed with the quality, especially the Stratos 2 triggers.

Lots of triggers group like this so you shouldn't have a problem doing this. I use PW III's with PW TT1/AC3 and TT5 all intermixed with built in PW receivers in studio lights. I've run up to 4 groups.....multiple lights in each one at times.

I have both. The stratos are rock solid. I also like the fact that you can mount a flash on the transmitter and also fire a receiver at the same time. Cant do that with the Cybersyncs but the cybersyncs havent failed me either.
