Wow!, nice, very nice!
Hopefully, you will be driving it with a Trinnov processor, it would do that gear justice, especially with four sides and 6 overheads.
You will be blown away with the 40xw as a center, it is the ideal config for a rig like yours.
With the subs you list, you will have plenty of bass and mid-bass. Just make sure the calibrator is good, and that you have the room acoustic treatment sorted.
Please go ahead and start a new thread for your HT build-out so we can chime in on that. This one looks to be a fascinating one.
Agreed with Jonathan, sounds super cool ! Start a new thread on your HT set up so we can follow along ....... with pics !
