Giffels Rosetti Assoc were the original architects, why not get them today to redesign the place, updating the lousy 80's/90's modernizations, and return it to more of it's original retro appearance, especially the marble pylons over the driveway and the suspended glass room [[restaurant) overlooking Jefferson Ave.

This can be done with an expansion as well, and done fairly reasonably if tight reins are kept on the budget. Simple and elegant as it was built is the way to go- and knock down JLA and expand it out the back, and continue the riverwalk all the way down.
