Yanfly Party limit Gauge: Add Y position on condition

Hello! I'm looking to modify the plugin slightly for better looks in my game. I am looking to have the gauge go lower when the help window is opened, inspired by Yanfly's Turn Order Display.

Here is the code I found to modify:

Code:

Window_PartyLimitGauge.prototype.getPositionY = function() {
    if (Imported.YEP_BattleEngineCore) {
      var statusHeight = Yanfly.Param.BECCommandRows;
    } else {
      var statusHeight = 4;
    }
    statusHeight *= Window_Base.prototype.lineHeight.call(this);
    statusHeight += Window_Base.prototype.standardPadding.call(this) * 2;
    var height = this.windowHeight();
    return eval(this._unit.partyLimitGaugePosY());
};

Here is the code I found that would change the Y position of the turn orders:

Code:

Window_TurnOrderIcon.prototype.destinationY = function() {
  var value = Yanfly.Param.TODPositionY;
  if (this._helpWindow && this._helpWindow.visible) {
    var cap = this._helpWindow.height;
    this._selectHeight = this._selectHeight ||
      Math.round(this.contents.height / 4);
    value = Math.max(value, cap + this._selectHeight);
  }
  if (!this.battler()) return value;
  if (this.battler().isSelected()) {
    value -= this._selectHeight;
  }
  return value;
};

The end result would be that the gauge would lower by an amount I would change myself, but I don't know how I can achieve this. Any help would be the best.
