it was 70 degrees today, we're expecting 70 degrees or warmer tomorrow as well.
Unfortunately we're also expecting high 20's to low 30's one or both nights this weekend as well (with highs a balmy 36 degrees or so). Of course the forcasts could change by the weekend.
I figured I'd wait until the beginning of May (The last freeze date is sometime in the first or second week of May).
On a positive note, my wrapped fig seems to have made it through the winter with only a few inches of dieback on only the stems that I had to prune back to wrap. The unpruned stems look unscathed. I took the top cover off of them, but have left the majority of the wrapping in place (until I see what this weekend and maybe what the 15 day forcast shows thereafter).
If I get some time this weekend I'll try to put together a frame similar to what you suggest and try a couple cuttings that way (I've got some in perlite, a perlite/potting soil mix and others in bags already)

btw, I'm about 6 miles northeast of the Detroit City limits....which also puts me about 15 miles north of Windsor Ontario!
