This is somewhat garbled.  The point about the `kill' behaviour is that it
always means that the *next* operation on the kill buffer will
append/prepend instead of overwrite, if it follows immediately.

Thinking about it, it might be simpler to impose the -k behaviour and just
have the option -b for control.  This works much more like real kill
commands and you can do tricks with other (non-kill) zle commands if you
need to control the buffer.

Unless there's a neater way of doing it?
