We would like to know if it is possible to add mezzanine or half-floor levels to the tower for the architectural portion of the tower’s design. Furthermore, we wanted to clarify what the true scale of the tower would be, for architectural purposes.

You have complete freedom in your architectural design, as long as it is relatively consistent with the structural model. A mezzanine for architectural purposes is fine. For scaling you would have to establish a realistic story height for your architectural design and use that as your reference. Let me know if further clarification is needed.
