right this was just a total guess and probably will not work, since i dont hacve the XAS system, i can really do much but guess.

Code:

#------------------#
#Dod Change Leader #
#by:Dodoop #
#version:1.0 #
#------------------#
#
# Edited by: Night_Runner
# Date: 15/Sept/09
#
# Designed to: Turn on the switch corresponding with the leading player's ID
# (and turn off the switch from the last leading player). And update the
# leading player before battle (designed to be compatable with MOG XAS Hud
# V2.6.
#
#-----------------#
#Muda o líder quando uma certa tecla for pressionada no mapa.
module Dodoop
    #Tecla que devera ser pressiona para mudar o líder.
    CHANGE_LEADER_INPUT = Input::R
end
class Scene_Map
    alias change_leader update
    def update
    change_leader
   if Input.trigger?(Dodoop::CHANGE_LEADER_INPUT)
    leader_read
   end
    $game_switches[$game_party.actors[0].id] = true # Turns on the switch of
    $game_switches[$data_skills[0].id] = true
    # the leading hero
end

def leader_read
    $game_switches[$game_party.actors[0].id] = false # Turns off the switch of
    $game_switches[$data_skills[0].id] = false
    # the last hero
    @actors = []
   for i in 0...$game_party.actors.size
    @actors[i] = $game_party.actors[i]
   end
   for i in 1...@actors.size
    $game_party.actors[i - 1] = @actors[i]
   end
    $game_party.actors[@actors.size - 1] = @actors[0]
    $game_player.refresh
    $game_party.refresh # Needed to update the party order.
    @sthero.refresh # Only to be used with MOG's XAS, refreshes the HUD.
    @sthero.update if @sthero != nil
    @sthero.refresh if @sthero != nil
    @sthero.update if @sthero != nil
   if @sthero != nil
     @sthero.dispose
     @sthero = Window_HUD.new
     @sthero.x = XAS_HUD::XASHUD_X
     @sthero.y = XAS_HUD::XASHUD_Y
     if $game_switches[XAS_HUD::DISABLE_STATUS_HUD_SWITCH] == false
       @sthero.visible = true
     else
      @sthero.visible = false
     end
    @sthero.update
   end
end
end
