Buttressed Arch. Question for Ron N.

> 5.5 is beginning to sound more like it.

I agree, or even 5.0. Unless you decrease crown radii, 
increase rib number, increase rib depth, or all three, you're 
going to need the panel compression support. Ideally, the "all 
three" would be a better choice, but the go-bar deck would 
need an overhaul.
