There are lots of things that could happen. Most of them won't.
After flat tires, the next most common road bike mechanical failure is broken spokes. Are you going to carry spare spokes with you? How about a cassette cracker and a 12" crescent wrench because the broken spoke will almost surely be on the rear wheel. Uh - the third most common road bike mechanical problem involves bottom brackets. That tool kit is starting to get heavy isn't it?
After spending that much money to get yourself a really lightweight bike, it sounds a little silly to me to weigh yourself down with too much other stuff. Frankly, you should figure about double the weight of your tool kit to account for the burden of worry that you're packing along with you.
