Try the shareware iKey. It permits to invoke any key sequence by a shortcut of your choice.
BTW: Similar solutions for the Classic Mac OS are MacroKey and KeyQuencer (great, with AppleScript support OSAX).
In case one sticks to the footprint of the Keyboard II but needs real function keys, one might consider to get a MacAlly MK-96 keyboard.
