It turned out that address mode B was redundant as C with 0 offset (immediate) was the same (except for the underlying C code of course, but adding st->b is very cheap). This allowed B to be used for entity.field for all transfer operations. Thus instructions 0-3 are now free as load E became load B, and other than the specifics of format codes for statement printing, transfers+lea are unified.
