Iron cross with hands outside the rings

Do u guys think that doing crosses on the outside of the rings would be an effective exercise? like a substitute for cross trainers. and would you be able to hit the proper position with the rings rotated that way?

Jordan jovtchev does it at around 0:30

It is an effective exercise, but doing that solely to get the cross is foolish. Look in the "Rings" section for the sticky "Preparing Elbows and Biceps for Iron Cross Training". Coach Sommer mentions you can work the assisted cross pulls and static simultaneously with the progressions.
