A more accurate way to imagine it would be to just double the current core (11 - 18) then add ~ 15' of mechanical screening. I have 44 Monroe pegged at 377', making CPE 6 feet taller. However, the main roof of 44 Monroe is only 356', so CPE should easily appear taller since the highest point is along the facade.
Edit: The elevation of 44 Monroe's block is 1085' while CPE's is 1086', so there's another foot.
