Optimizing Linux filesystems for cheap flash drives

Is it possible to hack a special “cheap flash mode” into filesystems such as ext3/ext4/btrfs?
Such a mode could e.g. move the log + inode table + allocation bitmaps etc. to the "FAT" segment (either breaking the info apart from the block groups or maybe even using a single block group for the entire device). Plus it could set the block size to the expected FAT cluster size (after all, these filesystems do know how to use block sizes != page size). Possibly other optimizations can be applied.
