Any reason you couldn't do this?

var s:Sprite = new flash.display.Sprite();

var className:String = flash.utils.getQualifiedClassName( s );

trace(className ); // flash.display::Sprite
trace(myClass); // [class Sprite]

var s2 = new myClass();
trace(s2); // [object Sprite]

I don't know a way to avoid round-tripping through a String, but it should work well enough.
