Nice problem, but somehow I don't like black e3-pawn which is actually not needed in two of the mates at all. I made a following version: W: Kc4, pg2, pg7 = 3. B: Ke4, Qg5, Bh6, Sg6 = 4. Solutions: 1.Qg5-e3 g7-g8=Q 2.Bh6-f4 Qg8-d5 # 1.Sg6-h8 g7*h8=Q 2.Qg5-f5 Qh8-d4 # 1.Sg6-f8 g7*f8=Q 2.Qg5-e5 Qf8-f3 # But still also in here I don't like Qd5 mate, because f3 is taken twice. I think also this can be improved.
In the mate Qd5# wPg2 is superflouos, that might be a weakness in such type of light problems. With the intended mates it is unavoidable in this scheme.
But the main question is about the originality and then the economy. At least, all black pieces should be fully and equally used, if that is possible. An example: W:Pg7,Kc4,Pg2;B:Rh5,Ke4,Qf4;h#2; 3 sol.
