i tried FICLONERANGE via a python wrapper btw - it turns out, that i can only clone ranges aligned to block boundaries :(
BTRFS is very neat per se, but documentation and help (most of all in very niche cases like this one here lol) is not that easy to come by.
my plan would be to properly process the data set, and then make it available as a BTRFS snapshot... you can export btrfs send as a file as well for storage etc.
if all my tries to use BTRFS fail, i might to write my own tooling and virtual filesytem as well, but optimized for my use case (MPQ files and such).
thanks for your input so far.
