Re: I REGAINED access to Bitcoins in my made-up brainwallet!
What you're suggesting is called security through obscurity:

I trust my passphrase to be difficult enough.
i could say the same thing about my simple sha256 brainwallet. Quote
If you don't understand that one random character added to the passphrase adds more "difficulty" than 10 rounds of the same encryption, I give up 
i imagine you're not talking about step 3 in your algorithm:
Code:
3. Take this 6P encrypted key, add -1, use this as brainwallet and fund the compressed addy
a bip 38 encrypted private key is already long enough. adding -1,-2 and so on was your idea of having some type of way to generate extra addresses in a sequential manner. it doesn't really do anything for security. so we're back to where we started which is the original passphrase. if it's long enough, its not feasible to hack no matter what brainwallet algorithm you use. i think you would probably agree with that statement.
so the real issue is why we would need to invent a new rather obscure algorithm to do a brainwallet when we could achieve the same thing by just increasing the length of our passphrase with a simple sha256 brainwallet which is freely available using things like bitaddress or any online sha256 calculator.
