I know the original series vs the newer series and it is not a good match.
The series I used a pure ribbon tweeter which was very clean and could be a bit too bright.
The second generation moved to a Heil tweeter which is airy but a bit more laid back.
So this combo of mixing old with new would in my mind not be recommended.
