Good luck daytripper! I think that having examples of her work with you is wise. You can gauge how the conversation is going. If you think that the teacher would be receptive, then you can share. If you feel the teacher's defenses going up, don't bother. I think that humility and acknowledging her expertise as an experienced teacher are also good tactics. I think that diplomatically asking for work at her level is worthwhile.

A word of caution. I think that it is hard with little girls who want to fly below the radar. I have had two. Both of them (one introvert, one extrovert) used their skills to blend. If you had asked the veteran teacher, both of them were "fine" in kindergarten. I now know that it was a mediocre experience at best.
