I have started to implement this idea in a branch now:

Well, it all depends on what you do with the IDispatch pointer you received.
You can pass it to comtypes.client.GetBestInterface(pdisp), and comtypes
will try to generate the code if it find a typelib,  or you pass it to
comtypes.client.dynamic._Dispatch(pdisp) which will then use dynamic
dispatch.  That is also what comtypes.client.CreateObject() does, depending
on the 'dynamic=...' parameter.
