Others might have a better idea than this, but I would approach it like this.

Make a copy of the piece, at least the area where the holes are, and replicate in it the holes from the original to the precision you need.

Then I would fill the original piece with a mixture of epoxy and sawdust.

Once dry and sanded I would use the copy as a template to replicate the holes precisely in the now filled original piece.

Good luck!
