If you want to rotate single Channels of a Texture, prefer rotating it in Photoshop.

There is an extra need for Processing Power for rotating Bitmaps, but -which is really awful- there is a Bug in Addition:

When U use the Comp.Maps Dialog, you assume that the Maps get rotated around its Center, like the Dialog suggests.
Thats wrong. The Maps will be rotated around its lower left Corner, which makes it nearly impossible to place the Maps accordingly...

There's even a little Frustration when using different Image Sizes/Proportions for different Channels. When tiling Textures, Maps with different Sizes will tile in different Sizes. You can use Compose Maps to scale the Channels to the same Size, but this is time consumptive and very faulty and inaccurate.
Just use your Image editing App to Scale everything to the same Size. (except you explicit wish this 'overlapping' effect for creating more seamlessly 'abstract' areas of 'noise' ).
