Adding a mc from the library based on the users choice

Is there any way to do this? I only want one MC added with the same instance name based on the users choice.

if(event.target.name == “faceType1_mc”) {
var myFace_mc:faceType1 = new faceType1();
}
else if(event.target.name == “faceType2_mc”) {
var myFace_mc:faceType2 = new faceType2();
}
