Yes! I have been waiting for someone to do one of these for ages

. I'd have done it myself, but I'm already working on a few things.
Angel Scout fighter is relatively easy to do, as it's just a Valkyrie with one less gunbank and one less set of engines, so you could make it out of the valk with minor model changes, or maybe even minor pof file and skin changes (depends how the second set of engines is designed I guess).
Other than that, there's Grey Wolf 2009's Apollo prototype
here , and I
believe that the people working on the FSFPS mod have a large transport which was supposedly from that era, or at least, from the Great War itself (I know they have a picture of one anyway, do I assume there's a model). However, I know absolutely
nothing about RF modding, so whether it'd ultimately be usable in FS (I do know that there'd be a fair amount of converting involved if it was though). I don't know if they'd let you use it though, but since the mod seems practically dead, they might. Also, if that model Analazon's showing off get's textured, you could possibly get the use of that as well.
Unfortunately, I think that's about it for currently existing mods

. Keep at it though - I really want to see a campaign like this one
