----- there are rounding issues not sure how they get handled not important to covey the idea
There are no rounding issues with subsequent halvings of block subsidy because it's no arithmetic halving. The block subsidy is an integer value in Sats and is halved by shifting its binary representation from MSB→LSB by 1 place, filling with a zero from the MSB side. There's never a fractional part in this process created when you only count in binary Sats and Bitcoin only knows and cares about integer Sats in the blockchain.

While I appreciate new ideas, I don't see how your proposal solves the problem in the long run. It feels like an intermediate (if at all) approach which adds complexity but doesn't provide a real solution. And I'm not even talking about the problematic aspect of confiscating and repurposing (presumably dormant) coins.
You can think about the fictional miner Patoshi whatever you want to whom around a million mined coins are attibuted, if you agree with what
http://satoshiblocks.info is talking about. We don't really know if this is a single mining entity and if this was Satoshi or someone else. I mention this because why stop at the Genesis block and for whatever purpose "donations" are sent to it.
Who stops others to come up with a plan to "repurpose" those more than a million bitcoins, the majority still unmoved, dormant? This is crossing a red line to me...
I understand that you're a miner by heart and your personal situation puts a somewhat limited time horizon for your own coins.
When I first discovered Bitcoin in 2011 I was fascinated by the fact that I could mine bitcoins myself at home. So, I did. I set me a goal to mine at least one Bitcoin with my measly not-even middle-class GPU back then. Took some time, I certainly paid more for the power to run the GPU miner than it was worth the Bitcoin back then.
Guess what, it was fun, I learned a lot, I did some stupid things with the majority of those coins, the rest I hodled. What I could rescue from my nooby stupidity in 2011 and 2014, is now worth way, way more than I spent for power in 2011. So, overall a nice win for me.
Why do I tell this here? Well, I think I know a little bit about mining, but definitely not on the same level as the OP.
Do I have an idea how to cope with the deflationary block subsidy from a miner's perspective? Not really, not sure. It's the way Bitcoin has been designed and instantiated back in 2009 for a reason. I don't say, we shouldn't change it, but a change should be well thought out and a fix in the long run.
Since quite some time, Bitcoin mining is kind of an industrial thing (from my bystander perspective on mining). The majority of mining pools are big players trying to concentrate hash power by concentrating miners and their hash power into a small, quite finite number of mining pools, besides having own mining gear (not sure how many pools have their own mining hardware in addition to trying to attract external miners).
As long as mining is profitable such an evolution is very likely inevitable, quite the opposite of decentralization unfortunately. Mining concentrates at spots where power is as cheap as possible, hashing gear wins that has lowest J/Th efficiency, the big players have to continuously shift to most efficient gear as long as global hash power still rises. Smaller miners that can't run in this hamster wheel experience deminishing returns, sometimes to the point that they barely see enough ROI. You'll have to find enough noobs (of fools) that you can sell off your outdated mining gear that has been rendered unprofitable.
I certainly didn't think this through because for more than a decade I didn't mine any Mainnet Bitcoin because I know it's not profitable for me personally where I live. I don't have the money to buy recent and efficient mining gear (the new stuff is usually mostly ridiculously priced). I don't have access to competitive power prices, mining-wise. If I were to mine again, then just for fun and the potential kick of lottery mining. (Hell, yeah, we've seen some Apollo miners win a block, haven't we? LOL)
What's my view now? When Bitcoin price, block subsidy and tx fees don't give miners enough profit, likely big industrial miners with own gear will vanish. Maybe then it becomes more interesting for Bitcoiners to mine again in huge numbers, decentralized, not-profitable and therefore not with big power-hungry gear, but just to maintain a certain level of security for the sake of it, to maintain Bitcoin going on. Does that makes sense? Sounds a bit idealistic...
