Assuming you are in support of his former public position, I think you'd be shooting yourself in the foot by doing that.
We don't know his private position any more, and it may have changed. But I think it's quite likely that his opinion hasn't changed; he just isn't allowed to state it publicly any more. In this case, it would be better for supporters of this position to keep him in the cabinet, where he can at least have a private influence. Consider this: if we could get everyone in the cabinet to share his opinion, we wouldn't have a problem any more. We need more David Davises in cabinet, not fewer.
The MPs to vote out are all the ones who are publicly in favour of the Snoopers' Charter. We can be far more confident in having an influence in our favour this way.
There is no restriction on where you must live to stand for parliament- I encourage you to stand against him!
Although, I would concentrate on Theresa May herself (I considered doing this at the last election when all this was mooted but blocked by the lib dems, but I stood where I live instead.)
