Big Daddy,
Combining the hub with the stiffener would be a bad idea. To keep the Douglas wheels you have to keep a standard bolt pattern setup. If you want to be able to change wheels then the stiffener/hub combo must unbolt from the wheel. A stiffener that is removable is severely compromised.
If we go with Jack's idea next year that probably means custom wheels and it doesn't matter anymore.
