Just nest the radials if you need more space. Very dynamic design - only include the buttons that are active/needed, if there are more than 8 then group them somehow for overflow, ideally predefined how to overflow maybe with a unique group icon
IMHO anything beyond 8 icons in a radial menu (so not talking about the current corner menu window for miniions with tabs and such) would crowd it too much for easy selection, and alternative selection like mouse wheel, numpad, directional pads, etc. Think cardinal directions on a compass (okay, and technically the ordinal directions). Gets ugly at the north-north-west stage.
Also, go to bed! That's where I'm heading and I'm six hours behind you!
