Yes. It is possible. I have done the following in order to generate
image with multiple partitions.
1. I wrote a custom image_types.bbclass in order to generate
multiple partition images (say /, /var etc)
2. Wrote a bbappend for base-files recipe to generate custom fstab
file with required partition's mount options
3. Extended grub-native recipe to generate core.img and boot.img
using grub-mkimage for target platform
4. Wrote a python task to join all these generated images (boot,
core and filesystem images) and embedded the partition table
structure into it.
5. Added this task to my image recipe after the 'do_rootfs' task
This way we can generate a custom image with the required partitions.

Awesome, I will take a look at this.
Thanks!
