Maybe you could put some code in mode B's hook to disable mode A if
enabled already and then enable it?  This way you would be ensuring
mode A always gets enabled after mode B, thus shadowing mode B's map.

Then you need to make sure that mode A's keymap appears before mode B's
in minor-mode-map-alist.  You might be able to do that by loading mode
B first, or else by adding a check somewhere to see which one's first
and reorder them when needed.

Clearing keybindings when redefining a minor mode map

[Leo Alekseyev]

Greetings all,

Suppose I have a keybinding that is shared by two minor modes (mode A
and mode B).  I want to accomplish the following: if both modes A and B are
active, then the keybinding should only invoke mode A's command.

My original approach was to insert code in mode B's commands that checks if
mode A is active, and if so, it creates a new keymap for mode B, with
conflicts removed.  Unfortunately, even though the new map is created
properly, it
doesn't remove the old keybindings that are in conflict with mode A.  Is
there an easy way to clear those keybindings?
