Thanks for the word of caution, I'm aware of that. It looks like the ends go through the stucco walls. I'm guessing there are beams there supporting the ends but I don't know that for sure.
I'll be wrapping the straps around the beam, so I think that should work great. Only thing I might have a problem with is getting the ends at a 30 degree angle since the space is only 12' long.
