Would you try?
What are the benefits? ... and the setbacks.
I find this matter of yours very sad, especially the Electrum wallet key you wrote down on paper is good but should have been kept carefully. Maybe you could save it in a diary it seems pretty safe. But it would be best if you write it down in a diary and keep it in a safe place inside your cupboard, but you can't remember it now because if you keep it in your memory, you could lose your wallet if it's the slightest mistake. So you can write two to three ways on a piece of paper and keep it under your control and in the right place so that it doesn't get lost.
But I write down my wallet keys in a diary and keep it safe enough. So that fire, water, wind, they are kept far away. But if it is destroyed by a single earthquake, then I will have nothing to do. But I've never put it in google mail so I don't know how secure it is.
But I will create a very strong mail later and store it there, because will it be enough for future security?
