If Shisui was alive all this time then he would know that Sasuke didn't know anything about the truth and saw the outcome between Sasuke and Itachi. While this hooded man does have a connection to both Akatsuki and the Uchiha (or mainly Itachi anyway) I don't think Shisui is involved.

Shisui suicide reinforces the fate of what Danzo felt was needed in the ninja world. Shisui was a martyr not an avenger. I'm in the opinion that it was Ramen guy.
