You should look for file/directory-level tree merging, e.g. this FUSE based
virtual FS:
https://romanrm.ru/en/mhddfs
Or various other unionfs'es, some of which are kernel-based.
Regarding btrfs, AFAIK even "btrfs -d single" suggested above works not "per
file", but per allocation extent, so in case of one disk failure you will lose
random *parts* (extents) of random files, which in effect could mean no file
in your whole file system will remain undamaged.
