There is a lot of guess work on my part here, but from what I have been told and understand, a lot of what you are describing is what will happen. The "fabric" portion represents about 2/3 of the roof, so there is a lot of live and dead load on it, (dead load is essentially the structure's own weight, and live load is a design variable. Snow load is often included in live load, but sometimes pulled out as it's own number). The rigid portion is by Sala's numbers 1/3 and therefore, the truss depth will be somewhat balanced. The load is less, but the span is longer which should create a scenario where the truss is deeper, but lighter (thinner) members. To reduce the span, I believe they will go diagonally as the renderings all imply, essentially from the 50 to the middle of the endzone.

For sake of comparison, the Vikings' stadium has one VERY large truss that essentially splits the field down the middle and the framing members attach to that from each sideline, like a ridge beam. This creates need for a very large column element at either side to support the truss load. That was used in the design to create the very large and glassy entrance. We have no real estate for such a structural element to come to ground which is what drove the solution currently being built.
