Rocket XW support

I want to use an M5 Rocket + Titanium 120° Sector with three 5GHz Nano Bridge devices for Lake Havasu City AZ.

I'm told I probably won't be able to get any of the old XM Rockets.  I see that lots of XW testing has been done, so I wonder when I can start my project? Is there a GOOD chance of the nightly build working?  I'm cheap and don't want to brick a device, but I'm willing to test.  

(I've read that in the crowded SoCal area 5GHz is often back haul. We don't have 22 million people here in the desert. I'd like to avoid 2.4GHz for our build here.)
I have an NSM5 node, but we'd like to grow.

Thanks, Charlie KØTAN
