I have been considering a Gundam/Macross mod for ACTA, but the one problem I foresee is that fighter level craft are the main focus in these shows, whilst ACTA keeps fighters basic. I suppose it could be worth shifting focus though so that the mecha/fighters use the capital ship rules, and the fighter rules could be used to represent detachable weapons such as the DRAGOO system. This would however mean that the show's capital ships would be beyond the scope of the game.
