c++通过模板化基类重写祖父类方法是一个好的设计吗？

Question

要求：第 2 层需要更改祖父类（即 Base）的一些功能。此更改的功能对于 Dervied_Layer_2_Case_A 和 Dervied_Layer_2_Case_B 是相同的。

您认为使用以下类型的解决方案有任何负面影响吗？我问这个是因为我以前没有见过这样的模式。

struct Base
{
        virtual void doSomething() {  ...  }
};


///// Layer 1 ////////////////////  
template <class BaseType = Base>
struct Dervied_Layer_1_Case_A : public BaseType 
{ 
       static_assert(std::is_base_of<Base, BaseType>::value);

        //This class uses other functionality from Base. Hence the derivation

        void runA() {calls BaseType::doSomething() while working}
};

template <class BaseType = Base>
struct Dervied_Layer_1_Case_B : public BaseType 
{
       static_assert(std::is_base_of<Base, BaseType>::value);

        //This class uses other functionality from Base. Hence the derivation

        void runB() {calls BaseType::doSomething() while working}
};

////////Layer 2 //////////////
struct BaseLayer2 : public Base
{
        //Only below behavior need to be changed. Other functionality of Base used without change
        void doSomething() override {  ...differnet implementation..  }
};


struct Dervied_Layer_2_Case_A : public Dervied_Layer_1_Case_A <BaseLayer2>
{
  //some of the functionality of DerviedCase_1_A is changed
};

struct Dervied_Layer_2_Case_B : public Dervied_Layer_1_Case_B <BaseLayer2>
{
  //some of the functionality of DerviedCase_1_B is changed
}
