I would not feed your ATB lizards at all, it will be nearly impossible for you to get her on rats/mice at that point, live or F/T.
I used to breed ATB, i promise that she won't starve herself to death (if she isn't ill), my snakes went 2-3 months without eating during the breeding season and they were fine.
I would look on your local Craigslist or Kijiji for live feeders, or buy a "pet" mouse from PetSmart without mentioning what it's for. ATB are pretty hard to switch over - Maybe try "braining" a freshly killed pinkie or fuzzy, basically what you do is crack open the skull of the mouse/rat then offer it to your snake.
