Is that possible with After Effects ?

I imagine the existing idents are motion controlled cameras filming the same location with different setups/lighting/times of day.

As long as the balloon is in the same kind of position in the different sets of footage, and the footage is large enough to allow cropping to position everything nicely.  You could probably get a drone to do a full 360 around the balloon each time - and then edit it together with the lens effect used on the existing ones.

More likely to be Nuke, Smoke or DaVinci Resolve than After Effects though these days.
