Collect called methods into mocked object in Kotlin?

Question

I would like to create a class B, which is "mocking" some other class A, i.e. having the same set of publuc methods, but doing something different with calls to these methods: instead of executing them, it should rememeber them in the list and execute egainst A at the desired moment. I wan't this not for testing purpose, but to create a type safe builder for A. The problem is that constructor of A requires some obligatory arguments, so usully it is called in the beginning. I would collect all calls in builder and then would call constructor at the end of builder.

Is it possible with Kotlin without manually rewriting delegates of all methods of A?
