I don't think so. Wonders are player-related.

I'm against cheating from extra knowledge. But I also think, if you have
mananged to send a caravan to a city, you are allowed to know, whether it's
the same island or not. And if you've managed to build Bach's, you are 
allowed to know which cities are on that island and effected by Bach's.
