i believe you should be able to create your own image type class for
that. maybe a generic solution might make sense for OE in general..
but adding a custom type that creates multiple images should be simple
to implement.

an example of such a custom image type class that comes to my mind is:

https://github.com/shr-distribution/meta-smartphone/blob/shr/meta-android/classes/android_image_types.bbclass

so basically, you can look at how IMAGE_CMD_ext4 is implemented in OE
core, and extend it to create multiple image for /opt, /usr, ...
