Later Agincourt designs might adopt triple turrets

Would Britain keep twin turrets on later Agincourt-type ships or move to triples?

It might adopt triples if the three-turret arrangement proved attractive in service and design work.

The initial reconstruction uses three twin turrets because that is the conservative choice for the proposed ship. Later development could move to triples. Acceptance would depend on whether designers and operators liked the three-turret arrangement enough to preserve it while increasing the number of guns. Turret evolution would follow experience rather than an automatic preference for more barrels.
