Alice in Wonderland has been covered by scaffolding for two years now. It's getting embarrassing already. Come September, the ride should be closed down to reconfigure the vine sequence. Personally, I would change it by creating a false hill underneath the track during the vine part, just like in this concept art.
Rock work could come up to the track to create a garden environment. I personally thing there is no way to keep the vine as is while maintaining the aesthetic integrity.
