Yep you can do that.  That is what you do to the thicker manifolds.

Yep, these are available from almost everyone that makes EGT's

Not really but what you can do is drill a hole and then weld the bung to the
manifold and it will take the stress instead of the manifold.  If you are using a
manifold that is readily available for cheap, I'd just drill and tap it.

Hope that helps,
