If you can't calculate the load, then you can't know if it's strong enough. You need the span, the snow load, the dead load, and the roof area that you're carrying.

Just eyeballing it, and not doing any math, I'd guess the weak point is now the little beams at the feet of the posts that hold up the ends of the trusses. There will be a huge bending moment in the center of those. CB.
