In a tty, TAB and C-i can't be distinguished (at least, most/all
terminal emulators will send the exact same byte sequences in both cases
by default), so there isn't much you can do there.
But in a GUI session, you could add something like

   (define-key input-decode-map [?\C-i] [control-i])

This way, `tab' will work the same as ever, but C-i will now generate
a new event `control-i' which you can bind to any command you like.
