I have done pin block repairs in the past. You want to fill the hole about half way up with an epoxy, and drive the pin ion. The epoxy then has to fine a way out, and the way is into the cracks, and around the pin. For better results, drive in a 2/0 pin, and after the epoxy has dried, remove the 2/0 and drive in a 3/0 pin. The torque will be a little snappy, but the pin will hold. I have done this kind of repair on a whole pin block with good results. It is a good fix on a piano that needs a new pin block, but where the customer doesn't want to pay for one.
