What exactly is a problem? We've done this in different kinds of settings. 
Generally, it's very easy to do multiple images (separate tasks with lists of 
all you need for those images, one "container" image for other images if 
needed, interdependcies via do_rootfs (there was patch do it via DEPENDS, but 
it got reverted)), multikernel (for example, if you want to have one Linux 
kernel controling real hardware and another one fully virtualized) build 
doesn't work out of the box AFAIK, but can be fixed. Building hypervisor or 
microkernel is also not hard, you just need to add proper dependencies to your 
kernels and configure bootloader appropriately.
