Any way to play alpha past intended period?

I got in on the Nioh 2 alpha on PS4, which runs May 24-June 2. It requires you to sign into PSN to play it. Presumably this is just for verification that the alpha is active, as the game itself won't be on-line only. Is there any way to make it playable after the alpha period expires? And even if there's not at the moment, would there be in the future if the current firmware gets jailbroken? I know that the original Nioh alpha got changed quite a bit, but I wasn't following it at the time,...
