Thank you, That's I asked ACube to do but your solution is better. However it's still very very long and you can't resonably finish with such an algorithm on the 3x3x3. Another possibility is to fix the centers at the beginning. But then it just goes back to a normal Fridrich Solve.
So I guess I won't look much more into that possibility, maybe I'll from time to time do the cross on one side and fix the center but it needs to be a very lucky case then.
