I like most of the ideas, though I agree they don't needs to be as extreme to improve the current layout. Smaller changes are more affordable and more likely. Tearing a lot (most?) of the Landing down would take too much time and money.
The model they had at the session was very nice as well, though I think that's a few years old at this point. If they were to ever add on to the existing structure, they'd need to tie in the roof style of the current Landing to match the new buildings. The difference isn't extreme, but it stands out when I look at those pictures.
Speaking of the roof, it would actually be nice to see the orange/coral-colored roof change. It reminds me too much of the Miami Dolphins. I say go with a plain silver color, or if you want to get all team-spirity, go with teal!
