We mostly need a large number of people attending as delegates, that enjoy getting noticed, deferred to, and hamming it up, to dress well, and pretend to be government and military reps any time someone speaks to them during the event. They will get to do things, but have no set lines or expectations otherwise. They will naturally be free to attend all performances, panels, etc. but are simply asked to show up to the 5 acts of the play. As little else is scheduled during each of those brief vignettes, that is more fun than burdensome. Only a few of these are taken so far.
We still have no rep from France, Spain, Russia, Austro-Hungary, China, Japan, or Portugal, which would all be glaring omissions. We have military reps for Germany, The Venetian Republic (Italy), and the Ottoman Empire, although some of those may not survive the play (it is a murder mystery) if others want to be seconds for them. We also have an Egyptian rep (civilian) and possibly Persian civilian.
They are supposed to pre-register, so we know they are likely to show up, and then if two people want to be the same delegate, I select the one whose outfit looks most suited to that country and offer a different country to the other, but none are turned away for this. There are many countries to choose from and at least one military and one civilian should attend from each.
I also need people to portray marine guards. As the group supplying these is a multicultural and multinational force, they don't need to look alike, but will have red sashes, possibly with gears on them if we have the time. (I have a machine that cuts metal foil into gears, but they have to be backed by something stiff or use gold painted leather ones to avoid problems with thin metal foil.)
They will act like guards and follow directions during stage performances, but again have few lines other than "Yes sir/maam, or yes Admiral" so no rehearsal is needed, and thus, I cannot expect to get free passes for them either. Local drama departments will certainly be contacted, but you may have steampunk interested friends that would like to do this.
