I would have no problem doing this for a week or even an event. But it would be very difficult to implement this into an entire militaryRP server because there are just too few addons regarding the revolutionary war. I've looked for muskets on the workshop and the only ones that are from that era either don't work or are no longer supported. I have also only seen 2 to 3 model packs in total for both sides, reducing the chances of having any differences in uniforms. Not to mention we would be removing much of what people enjoy about the server with our many vehicles and weaponry.
If we were going to go into the past I would say we should do WWI at the earliest. There are a few addons out there for biplanes, landships, and artillery that are already part of the packs we currently use. Anything in between WWI and modern times will have plenty of coverage.
