Reverse attributes values

This looks simple to do, but I had to use 2 BulkAttributeRenamer, 2 Counter, then a FeatureJoiner

for example, the below attributes values need to be flipped as the FROM_xx to be TO_xx as shown:

Source attributes:

FROM_X | FROM_Y| FROM_Z | TO_X | TO_Y |TO_Z

1|2|3|4|5|6

Output attributes:

FROM_X | FROM_Y| FROM_Z | TO_X | TO_Y |TO_Z

4|5|6|1|2|3

Is there a better way to do it?
