well, the main thing I am concerned about is your rigging points.
I would take it by i-beams, you are talking about steel i-beams. Chances are you're safe, but your insurance company might want to get a second opinion. At least you've done some due dilligence in being redundant and over-engineered.
Just keep in mind that over engineering won't replace proper enigneering.
May you never have an accident and may all your guests be happy. I would prefer things to remain that way above anything else.
