If /boot/grub can remain unencrypted (after all, it does not really
contain anything core.img cannot) you can simply install it as
mount /dev/sda5 /mnt
grub-install --boot-directory=/mnt /dev/sda5
using something like ext2 or FAT.
Of course your empty partition could also simply be an empty ext2
partition if Grub installs on that okay.
I don't know how big the smallest ext2 must be but I don't think very
big and no 1GB btrfs partition or anything of the kind.
Then using "my" patch you could even have a PV header on it and nothing
else and Grub would install on that also, I believe, although I haven't
tested on partitions, but that is nonsense if you can just use a ext2
partition right.
The PV header is also just one sector. But at this point because you
need a custom grub I would consider that a bit nonsensical if you can
just put ext2 on it?
