Bowtrusses, Cantilevers, and OWSJ

In my corner Yonge/Gould triple and double storey height spaces, I want to have approximately 10 meters span without columns at the end. I talked with you earlier and you noted that OWSJ cannot frame into Bow trusses, since that's not what bow trusses are used for. Do you have any other suggestions as to go about this?

BTW to my lovely classmates, there's a countdown for questions and hand-holding answers apparently... 2 left?
