Note that I meant prototype in the "working model" sense, not in a
"throwaway"/"proof of concept" sense.

The idea is to reuse GObject facilities where possible (e.g. types,
inheritance, signals, GValues), and simply implement the appropriate
vtable semantics overridable at runtime.  I was wondering if anyone else
has stumbled on this and already solved it.

Yes.  The problem with PyGTK is that it adds new C code for each GTK
class whose methods must be overridable from Python.  That works well
for GTK which is fairly static, but would be a hassle in a system with a
number of evolving classes.
