the answer has already been said, @sb "absolutely not".

there's no good reason to destroy bitcoin by introducing fiat redistribution policies.

if you are stuck on the notion of lost coins, you can at least tell yourself a story about the future of computing power catching up with wallets frozen in time. the network is forced to evolve over time, and you can imagine a point in the future, due to mythical quantum computing becoming reality or some other unexpected attack on the algorithm, where new users will move to better secured keys, but the wallets of lost keys, the currently dead bitcoins, could be brought back as technology catches up with them. I don't find that a likely outcome in the next decades, but over the next 100 years, seems at least possible.
