That seems like a hell-of-a-lot of work when you can just build a swinger yourself if you want to. Extending the front would move your center of gravity out front more, which is what extending the swinger does in the first place. But the plastics wouldn't fit anymore, linkages would need to be extended, and things that are mounted to the existing setup may have to be moved or modified.
It's a cool idea, but I think that this would have to be redesigned, that would need to be redesigned and that would need to be moved here, and that there. It just seems like a lot of work when just adding a longer swinger would do the trick. It would also affect turning and maneuverability because of the increased wheel base............. :beer:
