I'd prefer not.

We should aim only to have 1 super block per filesystem. Anything else
will lead to inode aliasing, and hence potential data corruption problems
when two processes try to write to the same file on different super
blocks.

Is there really any sane application that requires you to have different
rsize/wsize for the same filesystem?

Cheers,
