Remount doesn't switch filesystem drivers, it tells the existing filesystem
driver to accept new flags and/or a new option string.
To switch drivers you have to umount the old sucker and mount the new one.
(The idea of handing off consistent cache data from one mounted filesystem
driver to another... Ouch.)
Most filesystem drivers aren't compatible with each other anyway. Sounds like
what you really want to do is put the ext3 driver into "ext2 mode", and stop
journaling. Many people have wanted this over the years, but alas our dream
of "one darn driver for the ext# family" got squashed years ago because
people wanted two different codebases for the same filesystem that could
diverge, require the same bugs to be fixed twice, become incompatible...
