Access Visual Studio DTE members specified in DTE2 interface in IronPython

Question

Using IronPython 3.4.0 I can get the visual studio's DTE object using:

import System

dteClassType = System.Type.GetTypeFromProgID("VisualStudio.DTE.16.0")
dte = System.Activator.CreateInstance(dteClassType) 

In theory this object's type should implement DTE2 Interface but I can't access its members.

I do have access to the members specified in the older DTE interface

Is there a way I can change the interface I am seeing? In C# it would be something like:

Type dteClassType = System.Type.GetTypeFromProgID("VisualStudio.DTE.16.0");
EnvDTE80.DTE2 dte = (EnvDTE80.DTE2)System.Activator.CreateInstance(dteClassType);

But is this possible in Iron Python?

Tried from EnvDTE80 import DTE2 Tried clr.Convert() Tried subclassing
