I've been trying to figure out a way to make this sort of approach work.

Ok, I create a shared .NET DLL that defines the interface and all needed
classes. I can deliver a "C DLL" with LispWorks that is able to instantiate
the types and interface as well as register callbacks with these types that
it has instantiated.

The fundamental issue that I cannot work around here is that there is no
clear way to pass along the previously instantiated from the .NET
application through to any functions exposed by the Lisp DLL.
