Right: any attempt to change any part of the Merkle tree will eventually lead to an inconsistency somewhere up the chain. More Sophisticated Fee Structure Ethereum transaction fees are based off storage needs and network usage. Another problematic point is that the address field of a message is a variable, so in general it may not even be possible to tell which other contracts a given contract will call ahead of time.
