Alt/Az and a De-rotator will work just fine - BUT - you now have 3 drives trying to stay locked to a target instead of 1. ie you are adding complexity to a setup that you can more cheaply and reliably avoid. The Pro's use Alt/Az and derotators simply because it is a cheaper/the only option on large scope.

Cheers
