I think I might have seen a similar topic like this somewhere on this forum.
Can you throw more light on how you intend to do this? Otherwise, this can be considered a scam and a way that you want to use to smuggle money from victims of lost wallet assets.
Because I don't believe their are ways of recovering lost wallet assets, and if their would even be any chance of that it will be from the users device which might have create backup some how on the background of the device.
I think it is absolutely possible, I cracked 4 old wallets already. Yes - not possible with bruteforce power, it can be done only with precious work of collecting all information from user with forgotten password and mind of true hacker. Otherwise is total lottery.
This is possible if the wallet is personal. And not bought, it is not clear where and it is not clear from whom.
