Boss, will you or your engineer figure a way for a customer to get an opening to an attic that is two truss bays wide?
The vision I have is 24″ centers, a two-ply truss on each side of the opening, and a single truss on layout in the middle, with its bottom chord cut and headed off to the two-ply flankers. Headers are sized appropriately, and the cut chord ends are fixed to the headers with wrapped Simpson straps.

Here is a pic of what I described. I only modeled the bottom chords.
It is an attic truss situation, the span of which requires 2x8 bottom chords.
I built this house once already, and that time the truss engineer wouldn't go along with us and do something like this, and we had to ladder-frame the whole thing from bearing to bearing with 2x6s.
We will have the entire package panelized this time, and the panelizer will be furnishing the truss package. We have not begun the dialog yet with them, thus I am asking you know, just to see whether this can be done.
Oops. Here is the pic.
I doubt you're gonna get an engineer to go for what you described.
You could probably get them to go for a mono truss on each side of the opening, and maybe a smaller truss fot the top section.
