Give a thought to running without a center channel (doing it "phantom"). I was highly skeptical, even after experts and experienced user accounts of going without. I'm currently doing so as I find time to finish my center channel (4Pi speakers). I've got to tell you that these speakers sound so amazing and the center channel dialog is dead on. I feel like I should have heeded the words of wisdom and designed my room without a center channel. It is that good. I certainly couldn't do this with the Klipsch RF-82's I had before, or any other store bought speaker I've had (low end consumer stuff). The difference is that these kits are so much higher quality than you would get from a mass market speaker purchase of comparable price. Personally, I would pick the kit you are most fond of and build two channels. See how it goes and I bet you will be impressed.
