You don't add Hidden=1 to the code...you replace the width and height with Width="1" and Height="1". To use the default vitals, just delete the VITALS section (the follwing part is the vitals section):

<!--VITALS-->

  <Mapping ArtAssetID="opponent_vitals_backdrop_elite"                      FileName="Vitals/vital_elite.tga" />
  <Mapping ArtAssetID="opponent_vitals_backdrop_elitemaster"                FileName="Vitals/vital_elite.tga" />
  <Mapping ArtAssetID="swarm_vitals"                                        FileName="Vitals/vital_vs.tga" />
  <Mapping ArtAssetID="level_background"                                    FileName="Panels/inv.tga" />
  <Mapping ArtAssetID="level_background_red"                                FileName="Panels/inv.tga" />
  <Mapping ArtAssetID="selection_inanimate_backdrop"                        FileName="Vitals/vital_misc.tga" />

Of course, if you need the fervour/focus meter (champ/hunter), you'll have to figure out what to do with it on your own, since Daimon's UI places it over the player vitals.
