Did you look at or try mouse3.el?  It makes it very
easy to have your own contextual `mouse-3' menus,
whatever the context (a mode or anything else).

There are even two different ways to do define the
menu - choose whichever you want by a user option.

The default choice is to use keymaps to define the
menu.  The other choice lets you use a definition
specific to `x-popup-menu'.  The default choice is
more flexible.
