Y'all aren't using 100% of your brain power here. What Bandai needs to do is make an OVA where Suletta is trying to get to her wedding but first has to stop a terrorist attack (Let's say an Anti-Earthian group is trying to drop a space station on an Earth city) and she has to stop them in a new Gundam. Because this is a happy OVA she doesn't need to use a permet score and can just disable all the mobile suits by shooting/slicing their limbs off because she's such a good pilot, then she can stop the threat with the new Gundam's gimmick that's a giant magnet or something. Then she can land her Gundam in front of the church/building and hop out already in her wedding dress.
Boom. Bandai can show off a new product or two in the first half. We get our wedding in the second half.
Great, now I have to research how to nominate someone for a Nobel Prize, because I'll be damned if this isn't pure genius.
