I love the idea! As I mentioned in the Hoggit thread linked here, I would love anything that gives us the ability to make a more immersive world that's also customizable.
The ability to have a more modular set of things you can place to create things like FARPs or an insurgent outpost with individual walls, building parts, etc, would be a great addition compared to using the same repetitive model or tow.
I do hope that things like Super Carrier are going to lead to the ability to have moving and interactive ground units for places like airbases and just general troops on the ground. It would really be cool to be able to startup and see other planes/helicopters getting taxied around and send to the runway, while seeing other animations for things like refueling and arming the units.
