Thank you very much for your advice. I have read many warnings about the false security of brainwallets, and your link is one of the strongest & best ones.
To clarify, I havent decided to implement the wallet I mentioned...for now it's more of a learning exercise that I was considering.
1) The seed would be about a half-dozen "made up" words from a short story for children that I wrote many years ago, and never shared with anyone.. The "made up" words aren't real words in any language and as such, are in no dictionary and I've never heard them anywhere else.
My thought was to take those "fake" words that I remember well, and hash them as a string, then using a script, run the result through several thousand more hashes to generate a seed. It does seem like a lot of trouble compared to just writing down seed words, but this is a learning exercise for me, so it's largely theoretical.
2) Also, I didnt state the BIP39 question well, and I appreciate your clarification. My desire would be a segwit wallet, but my real concern is whether I could use the sha256 hash, or the resulting xpriv generated from the method described above to restore the wallet in Electrum in the future.
3) Question # 3 was more academic than anything. Assuming I used a cryptographically secure method to generate a random 256 bit and 512 bit seed hash, would I get any extra entropy benefit in electrum from using the random 512 bit instead of the random 256 bit seed?
Lastly, I see that you are connected with the bitcoinpakistan site. I have come across your site before and I think it is an excellent resource. Thank you for your work and help to us all.
