You can also save your words in a different language, that may confuse thieves too (for example https://github.com/bitcoin/bips/blob/master/bip-0039/spanish.txt).
However, if you start to make a very confused encoding in your seed backup, it may be more problematic to you to recover it later.
Another problem I see is about inherit. If you hold any significant amount of crypto, it is a good idea to give instructions to a family member so he can recover your funds when you pass away (if you have kids for example). And many bitcoins are lost because many people didn't believe that could be worth much one day. Maybe 0.01 bitcoin may be worth a lot someday.
If you have a complicate encoding for your seed, it may be difficult or even impossible for a family member to recover your seed.
I think the best option is still to hide that paper back up very well.
Or use multiple languages, that will confuse them even more
Best option is to carve your seed word on some metal plate,
so no water or fire can harm it.
You can buy them, or make them yourself, its not that hard.
