Можно ли создать шаблон только для одного метода класса?

class ClassName : IClassName, но это не совсем наследование, там немножко другая реализация). И интерфейс нужен в том случае, если нужно реализовать полиморфизм в коде и/или что бы упростить доступ к публичным полям в классах, которые реализуют этот интерфейс. static void Create()

попытался решить все через рекурсию
