AS3 - accessing and editing loaded swf movieclip from main movie

Question

    import com.hydrotik.queueloader.*;
.................  

public class Main extends MovieClip
    {
 private var _ql:QueueLoader; 

private function _loadSTRATIntro()
            {
                QLog.log("_loadSTRATIntro()");
                this._ql.addItem("res/swf/STRATIntro.swf", this.introduction_mc);
                this._ql.addItem("res/swf/STRATTransitions.swf", this.transitions_mc);
                this._ql.addItem("res/swf/STRATDisOrDat.swf", this.STRATdod_mc);
                this._ql.addItem("res/swf/STRATMultipleChoice.swf", this.STRATMultiChoice_mc);
                this._ql.addItem("res/swf/STRATAttack.swf", this.stratattack_mc);
                this._ql.addEventListener(QueueLoaderEvent.QUEUE_COMPLETE, this._onQueueComplete);
                this._ql.addEventListener(QueueLoaderEvent.QUEUE_PROGRESS, this._onQueueProgress);
                this._ql.addEventListener(QueueLoaderEvent.QUEUE_START, this._onQueueStarted);
                this._ql.addEventListener(QueueLoaderEvent.ITEM_COMPLETE, this._onQueueItemComplete);
                this._ql.execute();         
                return;
            }// end function

I need to get access to loaded STRATTransitions.swf from the main movie and remove some text from it. There is no source code available for the swf. Is it possible to accomplish? Thank you in advance for any tips.
