You can probably do it via track-mouse, but it's likely not going to
satisfy your needs quite like you want to.

That sounds reasonable, yes.

For text, I'm not sure it's worth the trouble.  For images, I believe we
do have something that goes in this direction (tho not for mouse

Another way might be to check for a `mouse-movement' binding on the
keymap under the mouse cursor.
