It is not possible to create DynamicMethod with Cecil and have no equivalent.
The dynamic method is closely related to runtime, and Cecil is completely decoupled. Two of them have a completely separate type system. DynamicMethod should be, well, dynamic, and as such should use the System.Reflection system, like the one available at runtime. Mono.Cecil has a different view of this type system, suitable for static analysis, without actually loading the assembly at run time. Therefore, if you want to use DynamicMethod, you must use it with your environment.
