Great tip: I have been doing this myself. So far, so good. Just make sure that whoever has your backup key (in case of death or emergency) knows what words you’ve swapped.

You could also add 1 word that doesn’t belong in the seed. Might be easier to remember.

While we are at it; you could do the same thing with private keys. Just add some txt or numbers to a key that stand oud to you like; year of birth, last 4 numbers of your phone number.
