Can we reduce coupling Capacitance effect in a bus structure by placing two nets adjacently which are driven in opposite directions?
 

You cannot reduce the coupling Capacitance however, because the coupling capacitance is a function of permitivity, the spacing between traces and the length for which they run in parallel.

I am curious... if this is a bus how can you reverse the direction of signals in two adjacent lines ?

Sorry if I didn't mention clearly.
Consider a transmitter and a receiver connected by a bus. So there is a possibility of two way communication between them, like acknowledge signal or any such kind of communication. I'm asking about such scenario.
