Is a Darth Vader film possible?

Rewatched Rogue One recently and... Vader is just so awesome in it.

Perhaps what makes Vader so interesting and fun is that, although iconic, he doesn't appear that much in the OT and PT. So when we do see him, it's exciting and fun.

I just thought that since technology is infinitely better since 2005 (back when he mattered to a main Star Wars trilogy) that we could get one? You know, with better CGI and fight scenes maybe??

Perhaps a solo adventure of him hunting Jedi? With a climax being a confrontation with Ahsoka? I mean, he had to have been doing something between III and IV right? The EU did expand on this, but those aren't canon anymore.

Also, James Earl Jones is 88. It wouldn't feel right without him (should he pass on, rest his soul), so if it were to be done, it should be pretty soon.
