Try to bring it sa machine shop mismo. It will depend how deep the spark plug hole is and the remaining part inside. They can use a reverse extractor tap or they can spot weld the remaining plug and turn it.
Did it once on a broken cylinder head bolt on a engine block that is still mounted. Syempre inalis ko muna cylinder head. Sa Roque Machine shop si Boss Mario ang napakiusapan ko. Towed it first thing in the morning by lunch time i towed it back.
