The question is if one designer is working for one specific theme only? Do they have any specialisation? If there can be guy like Samuel Johnson who works for both city and Ninjago (quite oposite themes in my opinion - and as we can see he is doing both vehicles and playsets), I highly doubt about it. So is there like only one really big team of designers? Or do they form team for one wave of one theme only and then do they form new teams?
I never heard of such page and I highly doubt that normal (not exclusive) sets are (were) done by one designer only, as it is rather team work ... However you can find information about designer with some recent exclusives , UCS, etc...
I really like your idea with revolving buildings (looks like something Lego would use in some official set). Using various scales is also quite clever, nice example of false perspective. I would definitely love to see some expansion in the future!
