Is it possible to use implicit casts created at runtime in C #?

Question

I am creating a type at runtime using Reflection.Emit. The problem is that whenever I create an instance of a new type, I have to use objector dynamic, because this type is unknown at compile time. This works fine unless I would like a different type to implicitly cast to a new type at the time of assignment. The variable happily accepts the new value and the corresponding type, without trying to apply it to the current type.

Is there a way to create a variable of the type just created that allows the use of implicit casting? I would gladly refuse to check the compilation time, but I would like these casts to be taken at least at runtime.

Edit:

Here is an example to make it more understandable. This is what happens when you know the type at compile time:

MyClass a;
//this calls the implicit cast operator and 'a' stays of the same type
a = 5;

and this will happen if you do not:

Type t = CreateTypeUsingTypeBuilder();
object a = Activator.CreateInstance(t);
//this does not call the implicit cast operator and 'a' just becomes in integer
a = 5;

In addition, I am not surprised at this behavior or ask why this is happening. I ask if there is any solution to achieve the desired behavior when it checks for an implicit statement at runtime.
