Honestly, I actually didn't know where to post this so Admin if I'm in the wrong place please move me.

When Forking Bitcoin / Other Alt coins would it be possible to Orphan certain blocks to reclaim the coins that could be lost or locked away such as wallets that have been inactive for 6+ years by causing invalidating the blocks and causing them to be removed by let's say a mini chain-split? I think this is possible personally but I've actually never seen it done before.
