It would be really cool if E.T adventure would get a refurb with the kucka arm from HPatFJ. The car would be much more open w no panel over your head or large walls on your sides and would have a bike handle for the handle bars. The entire ride would have to be changed, and universal wouldn't use 2 of the same ride concepts, because every year they try to improve on ride technology. This is just a thought I had.
That would require a lot more than it's worth to refurbish a more dated IP for what it's worth.
