In my illustrations as well as in the construction of my own mid-bass horns, I let the circular section of the 8" throat run all the way out to the mouth; it is tangent with the adjacent walls of the horn at any given point. If I understand correctly, in your case, because two of the angles are acute, your thinking is that those "corners" may benefit from a larger bridge. Looking again at the photo of your attic wall, I see that giving the horn a big enough mouth may require a small vertical fourth side at the outside of each horn, in which case the resulting angles would not be acute.
