I don't see how. It seems like the logical outcome from this is "whoever pays the most gets the next sidechain block"... That's not particularly useful for merge mining. > This enables sidechains in Bitcoin. There are different kinds of sidechains... Federated peg: this already works on Bitcoin. SPV/SNARK peg: this isn't enabled by your BIP. Drivechains: this isn't enabled by your BIP.
