After discarding the idea of encoding eight humorous messages, and without studying the rest of the protocol to see if these are already implemented, here are my suggestions for the three extra bits with a transmit frame:

HI James,

adding extra ad hoc messages can be easily done by using some of the unused existing message space. For example the directional CQ messages were inserted by using the unused callsign series E9xx. These sort of things require no extra bits, just global agreement.

With respect to your other suggestions, in the protocols as they stand every standard message except the 73 one expects acknowledgement. The 73 and free text messages do not expect acknowledgement although some free text messages can be constructed to imply acknowledgement is expected, "REPORT PSE?" for example. When acknowledgement is not received then simply repeating the last message until acknowledgement is received is all that is needed. It is unfortunate that many users wish to shorten the QSO sequences without regard for the above. There are some cases for dropping messages like the initial grid reply to a CQ when propagation is unstable.

I believe you are not thinking far enough outside the box with how an extra bit may be used. For example the current protocol is partitioned into two by a single bit. One half encompasses every standard message and the other half encompasses all the free text messages. A single extra bit opens up the possibility of a whole new protocol with a message space as large as the existing protocol. Using one or more extra bits to add value to the existing protcol would be missing a huge opportunity.
