I'd go for an aristocratic designation, something like 'noble(man/woman)', 'princess' 'royal' or the like. should even work with representation and universal suffrage, as reality shows that those do not mean to total abolishment of titles. just ... it would be funny to have such noblemen also perform spy activities like inciting revolts and poisoning water. but I guess you have to make compromises somewhere. alternatively, emissary or diplomat works for me too.
and if you really do start on this, don't get stick too much with any idea. the only reason I proposed something as complicated was that UU 1) have to replace some unit and the spy is one of few unit without combat attributes and 2) it should still retain some basics of the unit it replaces. losing spies altogether would be pretty harsh after all. I'm all in for other ways in such a direction, after all the end counts, not the means.
