I don't think its ridiculous, but I do also agree with Tom in that there's two things going on here and you have to figure out what you're wanting: 1) just actually photographing the owl(s) in the wild, regardless of how the photo turns out; 2) photographing the owls for the best image you can. One is like a milestone or achievement, one is dedicated image creation that requires several sessions. Nothing wrong either way, but it changes what you need and what to do.
Personally I think it would be an interesting tool to help, but ultimately, I would look for the owls nests and GPS them with a fairly accurate GPS handheld, like geocaching, and just start finding nests. Find those, and you find the owls. Then you can go to the nests, get their early before the owls get active, and hang out, looking for best position relative to the canopy cover, etc, for the best shot and angle. It may take a few attempts.
