No it's not possible. Didn't you think about it before you made that post?
However, Nintendo has did Arcade before. As such with classics like Donkey Kong or Mario Bros. Or even the Mario Kart Arcade game that had Mario characters cross-over with Pac-Man characters. But I don't remember Playstation characters being in an Arcade.
Only way would be a console that is designed for that game only. However, they'll never do it.
