If the plan is a fix once and for all, then that should be changed too.  It
could be set so that it is at least some multiple of the max block size

Alternatively, the merkle block message already incorporates the required

- headers message (with 1 header)
- merkleblock messages (max 1MB per message)

The transactions for each merkleblock could be sent directly before each
merkleblock, as is currently the case.

That system can send a block of any size.  It would require a change to the
processing of any merkleblocks received.
