Fraz,
You will always be the enemy in all of this - any compromises you make will not change this - she will just see this as a sign of weakness. Also much better to start tough and relax at the edges later than to start by making compromises and then try to tighten up once you realise you have lost control.
I can see the logic here, but the thing is, right now I am not the enemy, not for her and not for her congregation. They (the cong) probably still hope I will become a JW one day. And for example they are happy, I take care of the kids every once in a while, so my wife can go door-to-door. And for my wife I am not the enemy because we understand we both want what is best for our kids. And she is kind of open to the idea that the WTBS truth is not the one and only way to educate children. So she actually listens (and complies) when for example I talk about avoiding fear-inducing bible stories. And she doesn't side with the WTBS. Which I am afraid she would do more often than not, if I "start tough" now.
