It would be simple to integrate an ordering system that authority nodes would follow for block creation authorship. This would allow 1 authority transaction per block instead of requiring a transaction from each authority for each block round.
For example, implementation could use the tx.input field JSON to provide a field(s) electedAuthor.address/electedAuthor.block_number, where once the block has been validated that data can be used by an authority node to determine it's candidacy as the next block author.
