Not so fast!
ext2/3/4 does several superblock backups over the whole drive and
the directories are also distributed (but not replicated).
As the LUKS2 header is not that large, most data and structure
should be recoverable.
First step: Make a sector-image of the drive. Only work on the copy.
Second step: Find out how to recover an ext4 with overwritten start.
-> This is not the right mailing-list for that question.
But there should be fairly generic instruction out there.
Maybe there is an ext2/3/4 FAQ or recovery HOWTO?

Arno
