I have never tried this and I guess nobody did. But you may try and send
us a text to add to faq on MTD site :-)

One thing for you to keep in mind: use proper volume alignment. I am not
sure what is squashfs block size probably 512 bytes, then use alignment
512. In this case you will end up with 512-byte aligned logical
eraseblocks. this will make your life easier.
