Of course there's a hack...but obviously you are on your own.
You can edit the .scg file. Look for the SPACEPILOT section, then the button that is assigned to UI_ROT_TOGGLE (BUTTON_27_USER) and change it to any other UI_something from the BUTTON_NUMBERS or BUTTON_CHARACTERS lists near the top of the file.
You will, of course, get no feedback in the GUI.
UI_ROT_TOGGLE is a driver function. It works in all apps. The Right, Left, Top, Bottom functions only work in apps in which we can tell the app to change to a special view. We need an API function and a plugin, or a keyboard macro to do that. So those may not work in all apps.
Have fun.
