Ezequel,

could you re-summarize how the write support would be implemented? Read
entire LEB, modify data block (512 bytes), atomically write the LEB?
This would not perform well, but would probably work.

Or you want to avoid atomic LEB change and just erase the LEB and write
the entire LEB with the updated contents? This would probably be a bit
faster, but not power-cut safe.
