Unfortunately, that bracing is not stable.
Meaning it doesn't stabilize the top of the wall.
A single diagonal won't work. That is not a stable solution. You will need two diagonals coming to the top of the wall. Make one as vertical as you can and do the other at 30 degrees, give or take
That doesn't address bracing layout. Bracing layout is about making sure it's stable. If the one in place is near 45 degrees then install the next one as close to vertical as the duct will allow
To take the 5 psf load?
