3x2=6,3+2=5
The 5th solution is necessary for indirect self-unpin to fulfill the theme, but it would be nicer without it. It requires bBa8,bPa7 and wPa5 (instead of bPb6). The only interesting move is thematic 1...Sd4 but wS acts as a Dummy in the mate. It doesn't seem that excellent white mechanism is used in a best way.
An example:
White Kh8 Sd6 Sb5 Rd4 Bf2
Black Pe6 Qg6 Pa5 Kc5 Pf5 Ba4 Rb3 Ba1
