I'm not really answering your question here, but just out of curiosity what's the appeal of this approach over doing one of the options described at https://wiki.archlinux.org/index.php/Dm-crypt/Swap_encryption:

(1) dm-encrypted swap with a new key generated each boot (what I generally use, is the most secure, and works in any case where you don't need to hibernate)
(2) The same thing you're trying to do but with LVM instead of a GPT table
(3) a swap file on your Btrfs volume itself

I've done all these at various points and they all work well.
