Wow new listening room! congratulations...
Sounds great but I think the last thing you should worry about, after carpet installing is the TT rack. Will your new room be made of masonry, with concrete floor? and roof? This will make more of a change in your systems response than the TT rack, and of course more costly and you wont be able to change it in a couple of months if you dont like it.
What about something like this:

I do wish you the best on your project, which ever you decide.
PS. I use a TT rack made out of welded steel pipe and sand filled with great success, I have a 2 inch thick sand stone slab on top of it.
