You could just write a wrapper around /usr/bin/open and modify mailcap
to use the wrapper (or rename /usr/bin/open and substitute the wrapper).
I don't use MaxOSX but I've done the same thing on Linux. I like qiv for
viewing images and qiv uses file extensions. So I modified mailcap to
contain "image/*; fakeqiv %s %t", then created this wrapper. It only
handles jpg and gif, but could easily be extended.

  #! /bin/bash
  fil=$1
  typ=$2
  if [ $fil = ${fil%exmh} ]; then
    qiv $fil
    exit
  fi
  new=$fil
  if [ $typ = "image/jpeg" ]; then
    new=${fil%exmh}jpg
    cp $fil $new
  fi
  if [ $typ = "image/gif" ]; then
    new=${fil%exmh}gif
    cp $fil $new
  fi
  qiv $new
  rm $new
