If they make a city hub WELL, then I'd like to have it alot, but if they just make small loading sectors like in TDS, I'd rather not have it. To me, the city hub should just be the size of 2 levels combined in one... Have the thieve's highway, and make it really easy to get from one place to the other via the rooftops for those who want to just get mission to mission, and then let the people who ENJOY the city hub (like me) to travel the streets, pickpocketing random folk, and overhearing conversations and whatnot. Obviously there would need to be roof access for the fences and stores, but still, it could be done, and rather well.
Yeah, it COULD be done, and done well... but it would much more likely be screwed up beyond all recognition. The fact that you're using Life of the Party as the example just supports my case. The reason they were able to build a level that flavorful and awesome is because they didn't have to worry about building an entire city: they just focused on areas that you might see. For example, when you were 500 feet up in the air and couldn't get to street level without falling (and thus dying), they didn't need to put too much detail into the streets below - just graphics and a few wandering NPCs down below to give you the illusion of vastness. Can you imagine how hard it would be to create something that much fun if they had to worry about all the stuff IN those buildings as well? There's only so much game world that developers can build while still making it fun. Otherwise it just becomes like Oblivion, where you have a huge game world, but the inside of almost every house is one room (simply because the designers never had time to flesh out more).
What you're envisioning would be cool if it were done right, but it would take an impossible amount of resources to do well. Honestly, if anyone can pull off something like this, it would most likely be the fans, since only Thief modders have the dedication to put that amount of painstaking detail into what they do.
