Here is one possibility:
16 46.47 Mat41 1. Bd3 Ke3 2. Bf1 Kf2 3. c5 Kxf1 4.
cxd6 <HT>
16-> 47.33 Mat41 1. Bd3 Ke3 2. Bf1 Kf2 3. c5 Kxf1 4.
cxd6 <HT>
17 1:03 Mat41 1. Bd3 Ke3 2. Bf1 Kf2 3. c5 Kxf1 4.
cxd6 <HT>
17-> 1:05 Mat41 1. Bd3 Ke3 2. Bf1 Kf2 3. c5 Kxf1 4.
cxd6 <HT>
18 1:21 Mat41 1. Bd3 Ke3 2. Bf1 Kf2 3. c5 Kxf1 4.
cxd6 <HT>
18 2:26 ++ 1. Bc8!!
18 6:50 Mat19 1. Bc8 f2 2. Bh3 Kf3 3. c5 Kg3 4. Bf1
Kh2 5. cxd6 Kg1 6. d7 Kxf1 <HT>
18-> 6:50 Mat19 1. Bc8 f2 2. Bh3 Kf3 3. c5 Kg3 4. Bf1
Kh2 5. cxd6 Kg1 6. d7 Kxf1 <HT>
Bd3 and Bh3 are both mates in 41 at most. Bc8 is a mate in 19 at most.
