I think this would be easy for lego, and would be a great line of sets. It could be a new link between classrooms and lego. The Greats War would be very fun, but people would get pissed saying they would think the Germans and Austrians were Nazis... they aren't of course, but no one knows that sadly. I would be glad if I saw a package of Lego Doughboys and Germans brawling it our on the cover, the few people who adore this conflict would buy very last one. This would also be nice for everyone else, finally a real war, the guns would be real. This is a suggestion never said to Lego, so don't get your hopes up, unlike me ;)
