[Scripting Question] Disabling the use of revives in battles?

[Math0ss]

Is there a way to disable the use of revives in battles? I'm making a fan game with only double battles. If you only have 1 pokemon, the battles become 1v2, but if you use a revive on a second fainted pokemon, the battle stays a 1v2.
I'd like to make it so that reviving items can only be used outside of battles.

Put this after the page "Item_BattleEffects" but before "Main", or in a Plugin:

ItemHandlers::CanUseInBattle.add(:REVIVE, proc { |item, pokemon, battler, move, firstAction, battle, scene, showMessages|
  scene.pbDisplay(_INTL("It won't have any effect.")) if showMessages
  next false
})
ItemHandlers::CanUseInBattle.copy(:REVIVE, :MAXREVIVE, :REVIVALHERB, :MAXHONEY)
