It's kinda hard, since summoning process of the Grand Servants is known only to the counterforce, and it can be speculated that most of the grand servants are living beings and not ascended into the throne of heroes (Merlin is actually still alive in the tower of Avalon, while King Hassan exists at the boundary, before he abdicates his title).

Note that when we summon Merlin, he still is not a grand caster. That title still belongs to Solomon himself. He responds to our summon because he wants to.
