Total pie-in-the-sky, but I'd love to see a 2.5-mile underground people mover connecting the D (Purple) Line's VA station at Wilshire/Bonsall to the Getty Center, with an elevator shaft taking you straight up to the Arrival Plaza and the elevator box resembling NYC's Apple store on Fifth Avenue.
To finance and operate this, the Getty could hike up their parking fees, start charging admission (once they strengthen their permanent collection more), and work with Metro to create a special "Getty Center" pass. By that time, Metro should be developed enough to justify charging higher fares rather than making their services free to the public.
