@JacksonH Are you envisioning this crown as a 30-40 ft structure? Or are you envisioning this as a tall structure that could be a part of the skyline? My personal thoughts are that an oddly-designed 30-40 ft crown structure could be fun in a downtown park and be good for photos/a instagram destination for tourists (kind of like the bean in Chicago). But I don't see how a crown could work atop a taller structure and fit with the skyline's aesthetic.
I think the Space Needle, CN tower, Gateway Arch, Stratosphere, and Calgary Tower are all thought-provoking, skyline defining structures. For all of those skylines (Seattle, Toronto, St. Louis, Las Vegas, Calgary), I immediately think about that one structure when I recall how they appear... Meaning, to a casual observer, all other architecture begins to take a back seat at first look. So you better make it look great! Only the Gateway Arch and Space Needle have stood the test of time in my opinion. The other structures feel dated and a throwback to another time for me. But I'd be all for an interesting structure that could become a destination and observatory. There was one proposed a few years ago for Jacksonville that I thought had some visual interest - see below:
