I agree with Foxboy here. Lorelei works best.
As to having the medical instruments, the Trekkie instruments I've envisioned were more TNG-style. And in any respect, she'd keep them hidden via 'Ninja Magic' if she did keep them with her (which, due to the mysteries surrounding Ninja, won't be revealed).
Noah tends to seen Kasumi as a combat maid, rather than a Ninja/Kunoichi AFAIK. Kasumi and A.C. do not adversely change this impression.
