Well, I've never actually tried it, but it seems to me that
once you have your logical volume set up, there's nothing stopping you
from doing "luksFormat /dev/mapper/vg<x>-<y>" and encrypting the
thing.
The underlying geometry of the LV shouldn't matter.
The /etc/crypttab (and by extension the initramfs) should refer
to the device by UUID, so as long as all the LVM stuff is in the
initramfs, the kernel should be able to find it at boot-time.
