I can see them trying it, but for a period it was open and already had an exhibit/museum at the top... and it still never really got much of a line.
Like, I do admire SFMM for working to get this open... but kind of like all the Disney fans who had a cow when it was rumored that Lincoln would close, and there was a huge hue and cry... and it still plays (well, played since it's been closed for a bit) to mostly empty houses.
I see some parallels here.
