I personally would probably go with a build-in-build, and put some form of application rootfs on the emmc - this could either be a simple chroot or some more advanced form of container. This avoids nasty breakages and update problems when the filesystems go out of version sync. Other techniques might also apply depending on your software rollout process, like an addtional overlay fs, or a pivot-root with initrd, or.... it depends. But ripping out random packages and rearranging them at random locations certainly isn't a good idea. It already hurts when I think of the mount-and-deploy magic one would need for this to roll out in production. My $.02 Greetz
