I was thinking about something similar: Use a password which reminds you of your seed phrase. Like use the initial letters of every word + add some random stuff.

Typing a seed phrase in an internet-connected device you mean?

I use one seed exactly as a password.
Using it almost every day it's easier to memorize it.

Do you have a brain wallet?

I have one but I have to be more consistent in exercising it so I don't forget it in the long run.

Feels really empowering to know your seed words by heart!
