Parents really don't like war-type stuff these days, especially for young kids. Cops & robbers or playing war or anything like that—IDK about anyone else, but, like, the main activities of my childhood ages ~4-10, rivaled only by crashing toy cars and building LEGO stuff (often for war or car-crashing purposes)—is now gauche. Play like that happening at school can get kids in serious trouble, now, too.
Consider theming it to some fantasy thing about fairies or something.
[EDIT] Oh, but I do think it's a good idea, though.
