Here are a few reasons why it can't be Amanda:

1. Quiet appears to be younger than Amanda. Almost 10 years have passed since the events of Peace Walker, and Quiet seems to be about the same age Amanda was in PW, like late 20s or early 30s.

2. Your theory doesn't explain the disappearing mascara. It's not like Amanda could have gained that ability, just like that. It's clearly not something you can learn, not in the Metal Gear universe at least.

We're just gonna have to wait until some new facts emerge, I guess.
