How to switch weapons using the ninja mesh in jme3?

The ninja character that comes with the jme3 works well but I’d like to enable to ninja to switch weapons, prefeably to a nun-chaku or likewise. Is that even feasible or must I use a complete new model and the ninja model is just a demo? Is there any way to model the ninja in jme3 sdk, in blender or other way so that I can make it switch weapons?[java]

private void createNinja() {
	ninjaNode = (Node) assetManager
			.loadModel("Models/Ninja/Ninja.mesh.xml");
	ninjaNode.setShadowMode(RenderQueue.ShadowMode.CastAndReceive);
	ninjaNode.setLocalScale(0.06f);
	ninjaNode.setLocalTranslation(new Vector3f(55, 3.3f, -60));
	ninjaControl = new GameCharControl(1.6f, 9f, 25);// (2, 4, 0.5f);
														// radius (meters), height (meters),
														// gravity (mass)
	ninjaControl.setJumpForce(new Vector3f(0, 2800, 0));
	ninjaNode.addControl(ninjaControl);
	rootNode.attachChild(ninjaNode);
	bulletAppState.getPhysicsSpace().add(ninjaControl);
	getPhysicsSpace().add(ninjaControl);
	animationControl = ninjaNode.getControl(AnimControl.class);
	animationChannel = animationControl.createChannel();
	for (String anim : animationControl.getAnimationNames())
		System.out.println("Ninja can:" + anim);
}[/java]
