It seems that Samsung have done something like this with their RFS (Reliable FAT file system) that they use on a lot of phones with eMMC storage.
Unfortunately, their implementation has a lot of other performance problems and, worse, it's not even available under a GPL compatible license.

The software translation for the NAND flash is GPL.
