No.
Everyone can get any Great Building they want. It takes a lot of time, resources and friends/guildmates to do so. Well, some people also buy diamonds and get the goods and blueprints that way.
There are no other ways of building a Great Building, so it's not like some players are doing things others can't.
If you go through most neighborhoods, you'll see people at the bottom with few to no Great Buildings, buildings from several ages below their current one, improperly built special buildings (like peaces of the Indian Palace set scattered all over their city...).
Then, as you progress towards the top of the neighborhood, you'll see people with well organized cities, lots of Great Buildings with high levels and with some of them being from ages above theirs.
These players worked hard. Some of those who got their GBs by spending diamonds probably worked hard in real life, while most, who got their GBs through FP donations for blueprints and spent FPs to buy future age goods, worked very hard in the game (including me). They had to be patient, expand their in-game social network, plan carefully... Why would you want to punish such players?
It's mostly the underachievers who are bothered by such things. The game has been around for long time. Either be a part of the people who do this, or be a part of the people who, I suppose, get bored quickly, so they rush through the tech tree to experience new content. I'm sure your proposal will never be accepted for several reasons.
