It seems to me very difficult to get a bishop on 5c with the gold on 4b. If the gold is on 3b instead of 4b, this opening is known as the "Chikatetsu Hisha" (or "Subway rook"). The trick opening book by Mori Keiji has a small chapter on it. It seems like it was originally developed as a way to fight the Ibisha Anaguma. The book (like Terao-san) mentions Ito Hatasu as one of the few professionals who have tried this opening in professional play. The trick opening book is heavily biased towards the tricky side, so there is no good variation given for black. The general comment is that the Chikatetsu Hisha is hard to play because white will run out of moves if black defends correctly. This is all I can say, since I never really studied this opening.
