[SERIOUS] About Storing Crypto Wallet Seed Phrase in Password Managers

I know it's always said that the seed phrase should always remain offline, at most only on paper, never be introduced into a device other than the hardware wallet, etc.

The thing is, I have some concerns that storing it ONLY offline could be detrimental, such as if I needed it during one of my trips and didn't have it nearby. Also, I don't like carrying it with me on my travels because there's a possibility of luggage being lost, stolen, or even some security agent seeing it and knowing what it is.

So I thought of the following: why not store it in password managers (Bitwarden, LastPass, 1Password...), but in an even more secure way: adding more words than the original seed (e.g., if the seed has 18 words, add 24, so anyone with access will think it's a 24-word seed), and on top of that, changing the order of the words in a very strategic way that only I know and is very difficult to forget because I will periodically repeat it just as a precaution.

I honestly think it's impossible for me to forget the correct order, but even so, if that impossible case happens, I still have the wallet with me and just need to transfer the funds to a new wallet.

Honestly, just changing the order already seems super secure; the chances of someone discovering it are 18! (meaning that if someone tried 1,000 different combinations per second, it would take more than 200,000 years to get it). Now, adding 24 words, I can't even think of the probability because it's so low. Besides, the person would have to figure out that there are actually 18 and not 24. If someone tried 1 million combinations per second (1 MILLION!!!), it would still take more than 250 million years to get the correct combination.

p.s.: I don't think a hacker attack would be a reason for concern. With this shuffling strategy that only I know the correct order of, I think the words could be announced in Times Square, and still, no one would gain access to my wallet. Am I wrong? For example, here are the 24 words: [tragic arrow clean tray cereal assault advance glide cash snake resemble cricket helmet culture sand enforce demise narrow help quarter feature modify kangaroo situate] I'm sure that even if I said them out loud, no one could get in.
