Oh please...
How about sacrificing one keyseq and make your own keymap like this:
(defvar foo-map (make-sparse-keymap))
(fset 'foo-map foo-map)
(global-unset-key "\C-t")
(global-set-key "\C-t" 'foo-map)
(define-key foo-map "d" 'comment-and-duplicate-region)
(define-key foo-map ...)
(define-key foo-map ...)
Believe me, such keybindings will save a huge amount of time in the long run.
