Hi,
A possible way I can think of is:
1) Transform a polygon into individual vertices (Chopper).
2) Add sequential number to the vertices (Counter: use polygon ID as Counter Name).
3) Determine if vertex is 3rt or 4th one (Tester), and change z value of them (3DForcer).
4) Connect all vertices to re-create the original polygon (PointConnector: use polygon ID as Connection Break Attributes).
If you need to restore original attributes, consider using the FeatureMerger after.
