I don't think you can do that. It was my understanding that the lift-off ones are just a sheet of molded fiberglass.
Truth be told, I can work around having to take it off every time, assuming it's strong enough to be lifted by one person. If it's the kind of deal where you need four people supporting it so it doesn't crack in half, I'm screwed.
I distinctly remember taking the hood off my Fiero by myself a handful of times. Once I got the knack of it, I could just grab it in a bear hug and pick it up. That had a full frame to it, though.
