  <p>Several ideas come to mind. For instance, it may be possible to open the d-file, mating by queenside casting. Or maybe the king may somehow be shepherded down to the a1 corner, with a kingside castling.</p>

  Sadly, it looks like it can at least not be forced. Black can chose to lose in the 9.Bf4+ Ne5 10.Qd5+ Ke7 11.Qxe5# line, and there's nothing white can do about it.
  It is however possible to construct a full sound game tree where some of the nodes are castle mates, with all other nodes also leading to (regular) checkmates.
