1.)  Doing that is a bit dangerous if the data is important to a project
that is time-critical.

2.)  Shrinking one filesystem is easy, but the problem is growing the
other one, because you can only append to the filesystem, therefore you
can't use the space that freed up before it.  You MIGHT be able to play
some INSANE 'dd' tricks to move the whole partition back some arbitrary
number of blocks, but I'd only try that for fun.
