It depends what you want to use the potential for, and it is probably a 
bad idea. The bond constants are members of a parameter set, the *whole* 
of which may be a reasonable approximation to the whole of real physics 
because of the optimization process - there are no guarantees about an 
individual parameter being a reasonable approximation to part of real 
physics.
