Your best bet is probably to use an editor function --- not a lot
else happens before the history expansion so it's hard to do in the main
shell.

gimme() {
  LBUFFER='!?'$LBUFFER
  RBUFFER='?:%'$RBUFFER
  zle accept-line
}
zle -N gimme
bindkey '^xg' gimme

Type "foo" or whatever on the command line and then hit ^xg.

Note I have not made any attempt to add sanity checks.
