Unfortunately, this has not been implemented.
Library Part parameters and IFC properties are not available when creating expression-base Properties.
You can make a wish for this feature, we can vote on it and if it gets enough support, we can submit it to GRAPHISOFT for consideration.
If you do make a wish, please post its link in this thread.
