Just for the record: I've just added `prettify-symbols-mode' support for
(La)TeX to Emacs' built-in tex-mode.el.  If you run a very, very recent
emacs, you could activate that in AUCTeX using

  (setq-local prettify-symbols-alist tex--prettify-symbols-alist)
  (add-function :override (local 'prettify-symbols-compose-predicate)
                #'tex--prettify-symbols-compose-p)

in a function in LaTeX-mode-hook.  I'll add that do AUCTeX, too (if
p-s-m is available).

The above also displayes the _ and 1 as-is.  I didn't really test, but I
think `prettify-symbols-mode' can't really do this.  It can just take
symbols (in the syntax-table sense) and compose them to some unicode
character.  That doesn't suffice for what you are looking for.
