Whether that movie were to confirm that this Spider-Man universe exists in the same continuity as The Amazing Spider-Man movies or not, at least this would be a good chance for Jones to properly suit up as Black Cat and fight some bad guys.
However, Sony also has its own, separate live action Spider-Man universe going, albeit without the Wall-Crawler actually involved.
If Sony wants some star power on its side, perhaps it could talk with Felicity Jones about leading the Black Cat movie.
There were also plans for Black Cat and Silver Sable to appear in a movie together, but it was announced last summer that these characters would instead lead their own separate movies.
