Hi,
There are a couple of variations on how to build gable walls in single-story houses with cold attics. Some let the load-bearing studs run from sill all the way up to the sheathing, while others (prefab) deliver the gable wall and the gable peak separately.
Then there are those who build the gable wall just like the long sides and choose to place the truss at the very end of the top plate. The truss then aligns with the load-bearing studs.
If you continue with a crossing framework (lying 45x45 or 45x70), can you nail/screw directly to the truss's diagonal braces? They are probably not dimensioned for taking loads in that direction, but only tension/compression.
I'm primarily thinking about wind loading.
