Change parent of the class using instrumentation

I have a class called Client, it is extending Connection class, I want to make a class called KConnection which extends Connection class, and I want that the parent of the Client should not be Connection but it should be KConnection using bytebuddy agent in the premain using AgentBuilder(). something like this

new AgentBuilder.Default()
        .type(ElementMatchers.named("Client"))
        .transform(new AgentBuilder.Transformer() {
          @Override
          public DynamicType.Builder<?> transform(DynamicType.Builder<?> builder, TypeDescription typeDescription, ClassLoader classLoader) {
            return builder.superclass(KConnection.class);
          }
        })
        .installOn(inst);

Can anyone guide me over here..?
