It is an easy enough thing to do, but not done correctly, people can die.
Mount nothing to the bottom of the trusses except for the ceiling it was designed for.
Hang your beam from the top of the trusses.
That is all you can do by seat of the pants. Now you need a structural engineer to determing the loads. Not the load you think you will do, but the load tha yahoo after you will do.
Once you have the loads, you will know with sureity what can be done safely.
You may be able to reinforce selected trusses. You may be able to fabricate a truss for your I beam that runs the length of the beam so you effectively have a beam 16 inches tall. This means it can span a good distance without intermediate support. You need a structural engineer to balance all of this out, but I do not see it as a big deal.
You can't use a cherry picker?
