Does your proposal actually solve this problem?  Posting the 140 bytes of
data to the blockchain works as a public bulletin board because the actual
data within the block is what is ultimately guaranteed to be disseminated
to all participants.  With your proposal, a transaction with an OP_RETURN
containing a hash of data could end up being mined without the relevant
transaction ever even being relayed through the Bitcoin network.
