damaged file system

My RPi fell off the shelf, now the ext4 partition of the SD card is not mountable, automatic repair ran "force fsck" and says it is beyond repair.

There is a file or 2 I would like to try to get off it, is there any hope?

I put it on my Ubuntu 16.04 machine, I cannot read the ext4 partition, but gparted can see it.
I tried gpart; it could not read it.

What I have done on another Ubuntu 16.04 machine:

sudo dd if=/dev/mmcblk0p2 of=/home/don/Sdcard
sudo losetup /dev/loop0 /home/don/SDcard
sudo mkdir /media/don/rpi_card
Sudo mount /dev/loop0 /media/don/rpi_card

So, now I can read the files!

Is there a way to re create the partition with a new super block; since all of the super blocks were corrupt?

Maybe make a new LibreELEC SD card, then cp everything over?
