Dynamic adapter creation for static class from interface

Problem: I want to write test for an application that has many static classes with static methods, so switching a often used class to dependency injection is impossible in one step.

So I want to preserve the static class, create a adapter class with an interface that calls the static methods, so I can use this interface step by step for dependency injection. (as explained here: http://ift.tt/1Te2zf7)

But I don't want to write so many adapter classes for all the static classes so my question is if its possible to write a factory that will create a adapter class for a given interface type and a given target static class type e.g.:

// this is the problem
public static class CalculatorStatic {
     public static int ComplexCalculation(int a, int b) {
         return a + b;
     }
}

// I will write this
public interface ICalculator {
     int ComplexCalculation(int a, int b);
}

// I don't want to write this
public class CalculatorAdapter : ICalculator {
     public int ComplexCalculation(int a, int b) {
         return CalculatorStatic.ComplexCalculation(a, b);
     }
}

// This should create all adapters for me
public class AdapterFactory {
     public T CreateAdapter<T>(Type staticClassType) { // T is the InterfaceType
         // Do some magic and return a dynamically created adapter
         // that implements the interface and calls the static class
     }
}
