Finally, I've tried so many further (unconventional) approaches with the given stones, but all of them resulted in more than…
By removing stones (e.g. without bBh1) you might find other "valid" (shorter) solutions: 1.Qg8 2-5.Sf3-e1-c2-a1/a3 6.g1=S 7.Qf8 Q×d2# (via d1)
Without wPg6, we have an alternative solution: 1.Qg8 2.Sf3 3.Se5 4.Sg6 5.Sh8 6.Qf8 7.g1=R 8.Rg2 Q-d1xd2#
Without bBa5, we have a shorter solution: 1.Qg8 2.Sf3 3.g1=S 4.Se1 5.Sg2 Q-d1xd2#
