In a broad sense, yes. Drawbacks of this setup are the usual ones of
loop plus a deeper tree for logfs. Instead of having a single 'file'
with indirect blocks, you also have the inode file with indirect blocks.
So for every sync, another couple of writes are necessary that don't
give you any gains in such a setup.

With plenty of memory and sync being a sufficiently rare event, it
might.
