To get 55W and 58W on my 10 ft'er: I had to cut into the center-mount scalar and mount the titanium lnbfs almost jammed together.(One turned 180 degrees opposite the other ) It works satisfactory for what we needed. And both lnbf's fit under one nosecone.
I have a Titanium LNBF with a scalar that is maybe slightly larger than the titanium scalar, and a polarotor feed attached to its side for circular polarization satellites. The difference in dish aiming is about 5 degrees on my 10' Winegard Quadstar (F/D 0.35). So in my case if i wanted to get 113 and 117 I would indeed have to cut into the scalar. On a larger dish or higher F/D it might work without cutting.
