Hmm, I was actually curious how far one could stretch the Japanese origins of a servant actually. With Alice it was a weird one because technically she was named after the Einzbern family, but she has chosen to associate herself more with Japan (which fell closer in line with her father. Though thematically speaking, she is definitely more Einzbern-like than anything else. Class skills I definitely could have added in, but overall it does seem like Alice wouldn't be a very good fit for the theme upon further inspection.

With that cleared up though, I do have a couple other servant ideas now that I have a clearer understanding of things, though I would like to ask if you are willing to accept counterforce guardians? Specifically, I was considering Okita Alter (though she is extra class, Foreigner speicifally) or a version of Emiya as a servant. I figured I'd ask beforehand to guage how you view the involvement of the counterforce in this particular RP before I proceeded with any such ideas. There are definitely other fallback options I have in mind, which may help determine other masters I may make.
