I don't know if they will use The Punisher in
The Defenders. Krysten Ritter is saying that Jessica Jones season two and
The Defenders will be filmed very closely together though:

The Defenders/Jessica Jones
Speaking to Digital Spy, Krysten Ritter says that the Netflix crossover show and the second season of
Jessica Jones will shoot back to back:
They’ll be back-to-back. I don’t know if they’ll overlap a little bit. It’s about to be a serious undertaking. I’m starting my physical training - lots of weight training and boxing.
Meanwhile, she also teased the possibilities the second season could bring—including appearances from other Marvel characters:
I’m excited to see what happens next for Jessica, and the end of season one left a lot of doors open and questions unanswered. Kilgrave was her reason for getting up every morning. Saving people gave her purpose. I wonder how emotionally taxed she’s going to be now. That opens a lot of doors as to who will come out and play. We all live in the same universe, so there are endless possibilities.
