Hashes are impossible by hand...
Wouldn't a LiveCD on an offline HDD-less PC enough?

I haven't looked at the details of the hashing algorithm used to generate the public address from the private key. However, I don't think impossible is correct. I mean, everything a computer does can (in principle) be simulated using a very long tape and a pencil (see universal Turing machine).
Im just saying, difficult/tedious != impossible.
You want to play with semantics?
Ok, let's play.

Basic maths gives that Q > 1 - 7604/2^1000 = 1 - 10^(-297.149) > 1 - 10^(-297)
So R < 10^(-297) < 1/2^986
Yes, R < 1/2^986
TLDR
It's easier to crack 6 different bitcoin addresses with only 6 guesses than to a human to calculate a correct bitcoin address hash in his lifetime
Yes, I call that impossible
It's still easier to crack 6 different bitcoin addresses with only 1000 guesses than to 10 billions humans to calculate a correct bitcoin address hash in their lifetimes.
Your trying to increase the probability by multiplying by 10 billions proves that you really have no idea about the numbers evolved here.
Calculating something is also being sure your result is right. And that is precisely impossible.
