Yeah, sounds likely.
I have no doubt Tennant will return some time, he's a good sport, but I don't think he'd be interested in doing anything that is going to hurt the butts of the anti-SJW crowd more than they already are. He is good friends with Jodi and has praised her portrayal, so I think he would be keen to work with her again.
I've seen him interviewed where he has a good laugh at people who complain about the direction of the series, as a life-long fan himself he is astounded at the lengths people will go to trash the series online. I'll post it if I can find it again, suffice to say though, he would be rolling in laughter at this bullshit thread.
