It can be done without a twin:
Kg3, Nd1, Pd3 - Kh1, Sf2 (3+2)
I. 1.Sg4 Nf5 2.Sh2 Kf2#
II. 1.Sh3 d4 2.Sg1 Nf2#

Or
Kg3, Nb1 - Kh1, Sf2 (2+2)
h#2, 2 solutions - but without a pair of checkmates on f2.

@Laco but this lacks the thematic tempo moves by bS in each twin

I feel that better would be:

wKg3, Nc8 = 2. bKh1, bTd6, bSf2 = 3.

H#3, 2 solutions. 1. Sg4 Ne7 2. Sh2 Kf2#   1. Sh3 Nxd6 2. Sg1 Nf2#

Thanks Kenneth. I still think the author's intention is valid - to have a tempo move in the axis of the final move. The capture of bR in the second twin is a bit distracting. I prefer (b) Ne7 -> g4 maybe. bR still serves a purpose of eliminating numerous cooks. What do you think?
