[Q] Create device backup image via fastboot only topic

Hi,

I have two Q's.
One is installed with MC 11 and runs BubbleUpnp, it is basically a music streamer. Works just like I want it to.
The second Q is working, but the HDMI out is broken, so no video, which makes it impossible to set up.

I would like to know if it's possible to create a complete image of the first Q (with all apps and settings) and install that image on the second Q.
That would give me a second working music streamer, albeit without video.

Since the second Q does not have video, it would have to be via fastboot, I guess.

Any suggestions, links, tutorials? I have not yet found anything after some searching, so I'm trying here.

Thx
