To the question of unethical use, we are not talking of stealing somebody's money, this experiment is a part of something more bigger then just money)))
And what's the goal of this "experiment" ?
It could be to see if anyone has researched ways to weaken or break the cryptography of the encryption algorithms that would make cracking the wallets easier than brute forcing each wallet. Or, maybe the OP wants to know if someone has developed technology that can more efficiently brute force these wallet files.
