You can broadcast a replacement transaction directly to a miner if you know their IP address.
Whether any mining pools would consider that transaction, I've no idea. The standard bitcoin core client would reject the transaction (i.e., not add it to the mempool) since it would be considered invalid it includes one or more UTXOs that have already been spent.
And the fee for that replacement transaction, to be sufficient incentive for a miner/pool to consider it, would need to be at least as much as the next upcoming block could be. So ... currently 6.25 BTC + possible fees that would be mined.
And how does invalidating a transaction with just one confirmation and mining of a replacement transaction help you? Most exchanges and such are a minimum of 3 confirmations, no?
Yes, thanks. Indeed 3 or more confirmations are required. Maybe after 5 more halvings (0,19 btc of subsidy) that strategy could be affordable.
