Elven architect and Elven stats websites are independent from Inno. Inno has no control of them or of the fans who made them.
Even if we are to put this very valid idea aside by assuming it could be negotiated in some way, you are overlooking the secondary importance of the architect, which addresses the very point you are speaking to, Part 1 is knowing what goal you want to achieve, and just as important is Part 2: how do I get there!
A final design of a city (or building, or anything else) is useless until you have the strategy mapped out on how to achieve that goal. It is like saying I want to go the Chicago and not knowing in what direction you need to drive to get there.
The architect should be used to map out the interim steps (upgrade size change and roads needed) to get there. It prevents moving and upgrading yourself into a box and having to either delete buildings or buy expansions to get out of it. If you use the tool correctly it will show you how to get where you want to go as well as what it will take to get there.
One additional odd point is that in the architect you are planning for upgraded buildings and INNO is not going to let us just import the final form without going through all the research, upgrades times, and resource expense.
