If what you want is multiplying vectors, do you have any 
good/excellent/superior reasons for not using the standard built-in 
Mathematica function *Cross* [1]? (By redefining the dot product, or any 
other built-in functions, you have s very strong likelihood to broke 
your system.)

"Cross[a, b] gives the vector cross product of a and b."
