I am sure I could easily copy the rpms/kernel stuff over to it and then unmounts the real /boot and mount this new area as /boot.

You can do this (warning--back up everything first, just in case):
-download the grub live CD image (google for it)
-burn it to a CD
-boot it
-use the graphical partition editor to resize and/or move existing
partitions to make room for a larger boot then enlarge the /boot.
all this may take a while once you tell it to commit your changes,
but it isn't hard to do. I've done it several times, as well as smaller
changes, and have yet to have a failure (knock on wood).
Does it work with LVM? Hmmm... good question. I think so, but would
have to go check to be sure.
Good luck!
