Android 10 GSI should work, as it does on most treble compatible phones 
As @sm01man said, GSI are android related, so I don’t think it 'll be usable as it is for linux mobile distribution.
What you did on payload_dumper is awesome! I now have the stock A0110 images. I’m going to upload my script to have the OTA update. But I don’t know if there is personnal phone information in it, and I don’t like that much
