Done that.

It looks like it is not possible to publish Python types to QML (and use
the QML import statement) because QML uses a QObject's staticMetaObject
instead of calling metaObject(). That automatically limits it to types
known at compile time and no way to inject dynamic meta-objects created at
run time.
