Yes. Here is a proof game in 36 moves, which I believe is the shortest:
It can be done in 35.5 [bB can go straight to h1 without stopping on g2]:

Perhaps I should have specified that my proof game was the shortest with "white to move", as requested. But 35.5 is indeed the shortest without any constraints - good spot.
Short little position I made

SPG in 12.0 moves. Could be unique, although I'm not sure.
Yeah it's unique I checked with Jacobi
