A Possible Way to Re-Use Lost Bitcoins

[mandisa]

I have heard a thousand times that many bitcoins are lost due to the owners either forget their private keys, lost the hard drive, or simply die before they tell their family about the wealth. Although 21 million sounds like a lot, but with accidents like those keep happening, it's sooner or later bitcoin will gradually...be depleted. I know now the reward for miners are new issued bitcoins plus transaction fees, could it be possible that some day the reward includes a new feature, that all wallets will give a small portion of its balance to the miners, either a small percentage of the balance, or just a few Satoshis per wallet. So that "dead" bitcoins will slowly become global wealth for all humans again over a great span of time? What do you think? Is it a very stupid idea?

It's not a stupid idea but I don't really know how this idea could be implemented without loosing access to everyone wallet with private keys.
Actually there's simply NO way to recover a wallet without private key or passphrase...
