Kelsey, just making sure you've seen the patch in bug 1655101 too. I think it may be closer to what you have in mind, though probably not quite right. I accidentally un-needinfoed you while you were away and then couldn't re-needinfo, then I forgot about it. y. It hits a GL error on angle, which hopefully you know how to avoid with your fix.
