Yes, it is possible to get the same result using the approach you mentioned. Unfortunately registration of MenuKeyListener inside ToolTipManager is not enough. Also we need to generate new MenuKeyEvent with proper source (component) to let the tooltip manager know for which menu element tooltip text should be displayed/hidden (similar thing I did in my proposal, see processToolTipKeyEvent() method). 
I am sorry but I do not think we have to implement such solution since generation of new events is still necessary plus implementation of MenuKeyListener is required.

Thanks,
Dmitry
