It would be extremely controversial, but I wouldn't be against the removal, if only because I feel like the maintanance on the Orlando version is terrible and i've never liked our facade compared to Disneyland. It's a classic ride and i mean, we're running a slippery slope with talk of replacing pretty much everything.
However... while you mention a Tangled ride (and I agree it would fit well there), I think the best use of that space is to build on the backstage space that is for some reason unused and just a parking lot, which would open up the congested walkway. I would like to see a clone of the BatB ride from Tokyo. They're also building a Tangled boat ride. It could be possible to squeeze both in there if you use land efficiently. Now I know that that's all just a pipe dream, but I think that if we were able to get anything close to that on the Small World plot, then it would make up for the loss of IASW over time.
