You could edit the existing Location field to change the display order and maybe make it private and uneditable, then create a new field called Location and set the display order to "2". It seems to work but I don't know about showing up everywhere the default one does - probably some places depend on the fieldid being '2'. If that's the case it's probably possible to delete the original field then go to the database and change the fieldid of your new field to be '2' (or else just find the places using field2 and change them).

(BTW you could just delete the existing Location field instead of editing it, but this way you can put things back the way they were if you want).
