Wishlist: resized IMG file backup ready for SD card

I have been playing with my Allstar node and I love how it operates.

Something I wish it would do is create a backup IMG of the entire SD card running the node and reduced the size of the file (not a clone of the entire SD card), ready to be "burned" into a new SD card.
Similar to installing WPSD on a new SD card.
I also wish Allstar image on a new card would create it's own wifi network for initial setup similar to WPSD. This reduces friction for new users when setting it up.
I clearly don't know what it would take to make this work/happen but I thought I would put it out there for smarter people to consider.

Thank you to this great community for creating a phenomenal platform.
