If you have such in-depth knowledge of all the base classes then just call
them individually in whatever order you like and with whatever arguments
you like:

void Method(int arg)
    this->Base1::Method(arg + 1u);
    this->Base2::Method(arg - 1u);

However if you only know that you don't want to invoke Base4's function
then exclude it as follows:

void Method(int arg) continue(!Base4)
    continue(...); // This will do Base1, Base2, Base3
