Let her give it a shot, and make sure she has a good warm area to sit in right after eating. While they may seem big, they are probably just about right, and she'll likely go through a growth spurt right after making the switch.
It is very, very rare for a ball python to attempt to eat something that's too big, so try it out and make sure her basking/heated area of the cage is nice and toasty. With a suitable basking area, they can digest large meals with no problem.
