I wouldn't think it would. I mean, think of the langstroth and even though they are in frames, it's vertical. I've put top bars into langstroths already and they pretty much drew out the foundation as a triangle at first but then when it was finished, it looked like what you would find with framed foundation. I've seen pics from Robo who used barrels cut in half. The comb was drawn out rounded like the barrel. My point is, the bees will make their foundation to fit whatever you give them regardless of the angle type.
