Yes, that would be fine! You don't lose anything from transferring and the only downside is that you can switch accounts once per day (per device?), which isn't even that bad... It's not exactly transferring either? More like logging into your account with your code and password, meaning you would be able to access it from both your phone and your sister's at the same time.

As for buying diamonds on iOS you'd need either a Japanese debit/credit or iTunes card to pay for it in JPY, so using your sister's Android might be less of a hassle...?
