Some problems with that.
A filesystem does not incorporate any part of what's in your kernel.
Filesystems need not include anything much like a database. In some
filesystems (none that are Linux-native), the top-level directory is
named. And filesystems aren't necessarily based on directories at all
(though they usually are).
You might want to read up on block groups, superblocks, and inodes.
