Well, I have to admit, reading more of the comments and seeing the location has changed my view a bit.
1) If you've never used a medium format digital system, this is probably not the best time to test drive it. Even accomplished photographers will have some measure of learning when changing formats. Not saying it can't be done, I just wouldn't dive into it blind. If you have a week or so ahead of the shoot, extending the rental would be hugely beneficial for practice. (I'm assuming you're already a competent and accomplished photographer.) I'd also get input from the rental company's representative as to the best system and lens for this particular shoot.
2) As mentioned in prior posts, I'm a medium format guy, but if I'm in your position, I wouldn't use it for this. It's just not needed, and I have my doubts that your client will notice the difference. Remember: IQ doesn't necessarily follow image size. 60-80MP are awesome to have, but most images in coffee table books weren't shot using that kind of gear.
3) As for the scene, I think you'll have trouble isolating or removing all the people. That's a tricky move that will require careful planning and a number of exposures. Also, I think shift movements are important given the proximity to the buildings, but that is based on the look you'd like to achieve.
Recommendation: 5D3 + TS-E 24 II (with or without movements, it's a brilliant lens)
