Paul,

Any 24-bit RGB image is but three 8-bit grayscale images put together, 
one per color channel. All you would need is a plugin or macro that 
calls your required plugins over each channel individually, and then 
reassembles the RGB image. You can generate such a plugin with the 
macro recorder: open the Plugins/Macros/Record... , execute the 
required operations over an example image, and then save and install 
the macro.
