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.
If someone finds any kind of weakness in the cryptography algorithms used by bitcoin wallets to encrypt their wallet file the weakness is either disclosed safely and the algorithm becomes obsolete or they are going to sell the weakness to the highest bidding government to break the top secret information that is encrypted by the same algorithm (AES) by the governments.
Either case, there is no experiment here.
