Well, I've gone and done it.

I was changing out the water pump in my car and I busted off a bolt in the
aluminum block. So, I tried an easyout. After breaking that thing off in
there I decided to weld a nut to the little bit of bolt that was sticking
out. The result is now a bolt that is completely flush with the block and
it has an easyout broke off in it.

I'm thinking of just putting it back together and hoping that it doesn't
leak with the one bolt missing.

Does anyone else have any other tricks up their sleeves?

I did the same thing on my cast iron Jeep engine, but there was just
enough bolt sticking out that I was able to weld a nut on with a mig.
I have read in an old Lincoln welding book a technique for removing
bolts that are broken off below the surface. This book said to use a
stick welder, and to put the electrode down in the hole, and build up
the weld until it was far enough above the surface to weld on a nut.

I don't think you will get away with leaving one bolt missing.
