Well, the code of keyboard-escape-quit tests the variable buffer-quit-function.

So something like the following could work... 
(while at least keeping some of keyboard-escape-quit functionalities):

(setq-default buffer-quit-function
 #'(lambda () (message "Are you trying to quit?")))

Or you might rebind ESC-ESC-ESC like this:

(define-key global-map "\e\e\e"
 #'(lambda () (interactive) (message "Are you trying to quit?")))
