I am afraid that you are trying too hard to get the big things in the way. What you want to do is start little. Put small things in her mind and convince her that they are fine. This can be as simple as a quick look over to us or telling a little-white lie that "doesn't really matter anyways". Then use those little things to grow bigger and closer to us. That's the way in. When they open the gate for these, what they call, small and simple things you can then create a downfall slope to trap her in. It's the small things, not the large, that gets them started down the slope. Besides, a little nudge isn't as noticeable as a shove,
