Although normal children of a Container must be a IUIComponent, you can add a plain Sprite as a "raw child" of a Container:
var s:Sprite = new Sprite(); // draw into s.graphics // set s.x, s.y, s.width, and s.height myContainer.rawChildren.addChild(s); A raw child doesn't get managed by the LayoutManager, so you must position and size it yourself.

Quoting Alex, "Navigator children must be Containers, Container children must be IUIComponents, and UIComponent children can be anything."

You will need to add the > sprites to a UIComponent first. I think technically there's just an interface that has to be implemented on whatever you add (IFlexDisplayObject? IUIComponent?). If you extend Sprite or whatever and implement whichever one is needed, you could add it to a container. -Amy
