NO!!!!!!

please don't do that.

all (most) journaling filesystems log is the meta data (this is true for
reiserfs)   so while all the pointers are correct, the data may not be
what you expect.

powering down is like a seatbelt, even if you have airbags (journaling
filesystem) you still wear your seatbelt (powerdown properly)

yes, a journaling filesystem does result in a faster boot, because the
filesystem is correct.

the data could still be wrong.

but once, during your life, you must (this is a law, i've seen it
written down!) power off your system while doing a write, to prove to
yourself that your journaling filesystem works :)
