You'll need a code call to convert a name into a sound. Then, you use a random number to select the sound, fech that number index from the list, use the entry in the list to get the sound name and play it. So, answering your question, it is possible.
That's basically the logic. I know the call to get an actor type by name, but a sound by name I do not know. Someone else can post here the required code. I'm also curious about this.
EDIT: For a sound when the player hits the ground, the platformer kit should have something bout this.
I guess once someone post here the code call to get a sound by name, I can make a quick behavior to use it a upload it to Forge.
