Batmobile (Shield + Batmoto)

My concept is to create a batmobile with a shield as the first batman movie.
However it's very  difficult to create the same shield if we wish create a car with which our children can play.

I must create a new batmobile with : 

• A new shield and new items (Canon, energetic bombe , radar ...)
• A special bonus (my son wish a moto) : a batmoto

Note : The batmoto is a motorcycle and a plane.
