A potential candidate for Justice League

As said, the Waller-Wayne conversation can be connected to almost all upcoming DCEU movies in a number of ways. Thus, maybe Waller had a file on the Terminator as well. And maybe Batman will try to recruit him. This would be a scene similar to the Wolverine cameo from X-Men: First Class, though I doubt that it would be so funny.
In any event, this would also establish Deathstroke as a rather new character in the DCEU, one who hasn't clashed with any of the known superheroes before. And it would also establish Deathstroke as a character who can be redeemable and not just a straight-up villain.
It would also be interesting, since such a connection would lead to further appearances for the villain. Whether it would be in The Batman, whether it would be in a Suicide Squad sequel, or even in a Cyborg/Teen Titans flick, such a cameo would do wonders on the long run.
What do you think? When and where will Deathstroke appear in the DCEU?
