The ring limit (up to 16 in theory) is why I made my system resizing script convert everything to circle radius. It is attached to this post. It's a python script, and you will want to change the scale factor variable to the amount you are scaling the systems. You might have to fiddle a few times to get it just right, since SE5 will place systems outside the hex grid readily enough if you are not careful to make all positions inside it.
