Yes you can spread the piano wider and wider, but more importantly you can narrow it in a mix. Most mixes should not sound like you are sitting on the bench with the piano player listening to it, if there are other parts to the mix.

Example of narrowing: the piano is on the left side of a stage; you can have the highs and lows still have 'some' spread, but hear it mainly from the left side of the recording/mix (both the left/right channel panned varying degrees left) and still also have the ability to make one side louder if needed, like if you want the higher notes louder and less piano bass ...

Make your sound your own!
