As she is currently the first and only model of the Y4N product, they have been reluctant to try things out on her. However, hypothetically, she could have her appearance modified to change her body type or personality, for example. Although the Y4N bots are meant for more sedentary, less physically tasking jobs, internal modification to make them a bit stronger is a possibility (she is relatively weak). Research into her is relatively early (she is the first robot of her kind), but they'd like for future models to be incredibly customizable if possible.
