not sure if you can. Because i think internally Ctrl+i and Tab are
both rerpresented by ascii 9. (ascii 9 is named Horizontal Tab with
standard notation ^I)

similar other pairs i noticed are Return and Ctrl+m (which is ascii
13; ^M).

i might be wrong though.

Reference:

quote: «
 Control characters may be represented using yet another read syntax.
This consists of a question mark followed by a backslash, caret, and
the corresponding non-control character, in either upper or lower
case. For example, both `?\^I' and `?\^i' are valid read syntax for
the character C-i, the character whose value is 9.

Instead of the `^', you can use “C-”; thus, `?\C-i' is equivalent to `?
\^I' and to `?\^i':

     ?\^I ⇒ 9     ?\C-I ⇒ 9
