Have you considered using another event type in the array?

typedef struct sqKeyboardEvent {
	int type; /* EventTypeKeyboard */
	unsigned int timeStamp; /* time stamp */
	int charCode; /* character code in Mac Roman encoding */
	int pressCode; /* press code; any of EventKeyXXX */
	int modifiers; /* combination of xxxKeyBit */
	int reserved1; /* reserved for future use */
	int reserved2; /* reserved for future use */
	int reserved3; /* reserved for future use */
} sqKeyboardEvent;

You could have another EventType  (EventTypeTable) then use the other  
24 bytes for something else?
Pass up both the normal mouse event, then the extra data?

Also another consideration is just to do a plugin. I think you setup a  
plugin procedure to get called by asking the main event loop
to give you the events, then stuff on a queue
