Have you done this legendary checkmate before?

think so

Good checkmate. Now do en passant checkmate

There is a famous game Lasker - Thomas, 1911 (1-0)

O-O-O checkmate is not possible without playing the same person from both side or making the other person do that
it is a thing which is not possible in real games
even though i liked the game a lot

it is possible
but no one is going to play that duffer moves like that
so it is technically possible
but you are not going to find any opponent who will play that move combination to execute that O-O-O MATE
