Mike, I may be in the same position as you are, but can probably recruit additional help.
When I was working the dents out of my hood, I was wondering about the circular gap between the hood halves roughly midway back. Was that a balanced lifting point? If so, an eyebolt thru there (without the filler strip on of course) could be used along with a hoist to position the hood for installation. Just a thought. I would think that the factory would want to make hood installation easy, and they had lots of hoist capabilities on the assembly line.
I think that carefully placed blocking would work, or maybe a shipping blanket (free or real cheap ones occasionally offered at Harbor Freight) thrown over the cowl, and some sort of prop at the front to hold the hood up so you can get the hinge bolts installed.
Just getting the hood placed is definitely a 2 person job, IMO, but a third as a spotter would be good.
