Where is the load in relation to the ends of those joists? What is directly above the location you are installing this?

He is close to the wall AFA load goes. I can see your point if this was over an island.
When I said jacks, I assumed that some custom blocking/frame work would be required. Also, when I lift something heavy like that, I have braces on hand to hold the weight kinda like the stops on a car lift. Take the hood up 18' at a time with a simple car floor jack. I've done it so I know it will work. Too bad throw away 2 x 4's cost a fortune these days as I've bought as many as 10 for a small job like what you are planning.
Since it was mentioned and you confirmed that you will enclose the portion above the hood to the ceiling, I will 2nd the idea of opening up the ceiling.
Also, you may need to check the specs. Most hoods like to be within 36" of the cooktop. And, as you said, 6" beyond the face of the range. I'm 6 feet tall so I put my hood at about 74" off the floor. That's 2" more than they wanted but too effin bad.
You will find that while cooking you lean over a bit anyway, so I could have gotten away with 72" but I think I would have felt crowded.
