New Wonders - Any Ideas?

The wonders we have are OK I suppose, but that ain't going to stop me discussing new ones.

Great Wonders:

Final Solution - Eliminates all ethnic minorities, but reduces international reputation.

Small Wonders:

Imperial Coronation - turns a kingdom into an Empire. Increases happiness and reduces war-weariness. Made obsolete by Nationalism

Crusade/Jihad - allows the construction of hidden nationality units to attack. Made obsolete by democracy

Great ideas
I wish those could be done somehow.

Elevating 'final solution' to wonder status is a crime in itself. If you build it - every other nation should declare war on you for all time until you are destroyed.

Crusade/Jihad - Hello, I just found a can of worms...

BTW, Calgacus, wouldn't it be obvious where the hidden nationality units are coming from if everyone knows you built the wonder?
