The approach I usually use for superscripts is \u and \d, and to reduce
the size of the superscript a \s-1 and \s+1 or +/- 2 if it looks better.

The \u and \d move up and down by 0.5v.

For other up/down distances, you can use \v'e' where the value of e
determines the distance moved.  Negative moves up, positive down.
Default unit is v, as in \v'-.3v', or if you want it in points, use
\v'-6p', for example.  Of course if you subscript with \v'4p',  you must
balance it with a \v'-4p' to move back up after the subscript.

Same with using \u and \d.  They must be used in balanced pairs.
