I think Seaquest does something like what you are looking for.  The 
player's submarine is one sprite and the sharks or enemy subs are the 
second.  The missiles are used to create either torpedoes or a diver, the 
latter by shifting the horizontal position of the missile a pixel or two 
each line.  (I haven't disassembled it, so I'm only surmising this, but I 
doubt the ball is being used.)
