You're correct that it isn't optimal to have separate cities with separate types of great person points being generated in them. The most efficient method of generating great people at the fastest rate is to concentrate as many as possible of your great person points in a single city, with the National Epic wonder. This city you will probably want to be in a location where it can grow a lot (multiple good food resources and potential for farms), so that it can employ many extra specialists to further increase your great person point yield.
Of course, your strategy is equally valid, if not quite as efficient. It is always nice to be in complete control of the type of great people you will be getting. Personally though, after much experience with the game I've found that it's good enough for me to have a single powerful "great person farm" in which I can change around specialists to increase chances of getting a certain type (for instance, scientists). Of course, I'll still only have about a 60-80% chance of getting the great person I want, but in most cases this will still pay off. Even where it doesn't, I'll usually get a great person that was my 2nd priority anyway.
If you're trying out the "great person farm" strategy though, it's worth trying to build wonders while keeping in mind their great person point contributions. For instance, it could be worth building Sistine Chapel, Notre Dame, Taj Mahal etc in a different city to your great person farm (if you plan on building those wonders at all), so that you won't "contaminate" your great person pool with great people that you don't want. (In my case, these are generally Great Artists, which I usually try to avoid in all games except where I'm deliberately aiming for a cultural victory.)
