The rear chamber shape is not so much an issue, you can make it however you want. As far as the size of the flare is concerned, it's not necessary to make it any bigger if it will be used in corners as intended, but it won't make it any worse either. If you change the angle of the walls, that will change things, both in terms of radiating pattern and probably the shape of the response curve too.
