You could also run four different services with the same station configuration: 1. South LA to N Holllywood; 2. Westwood to Downtown; 3. South LA to Westwood; 4. N Hollywood to Downtown. This would provide more one-seat rides, while reducing frequency of each route. However, with cross-platform transfers, you can get the same service as the four routes listed above from only two routes: 1. South LA to North Hollywood and 2. Westwood to Downtown. For the last two trips listed above, you would have a cross-platform transfer, which would only add 10 seconds to the trip, plus the minor inconvenience of walking across the platform and finding a new seat.
I'm moving my response here since it was off-topic for the Crenshaw Line.
What you are proposing with building a second set of platforms for a cross-platform transfer is much more expensive and complicated than trying to open up the tunnels east of the station and adding switches (if that is even feasible) and having Vermont corridor trains share the existing platforms.
If you are adding two additional platforms (upper and lower) to serve the Vermont corridor, you wind up with the following:
Lower Platform "A" (existing) - Union Station to North Hollywood; Union Station to Westwood
Upper Platform "A" (existing) - North Hollywood to Union Station; Westwood to Union Station
Lower Platform "B" - San Pedro (?) to North Hollywood; San Pedro to Westwood
Upper Platform "B" - North Hollywood to San Pedro; Westwood to San Pedro
In addition to building the new platforms you have to be able to tie into both Purple line tunnels AND both Red Line tunnels west of the station. How do you propose to do that?
Engineering for the east tunnels aside, it would be much simpler to keep only two platforms with service like this:
Lower Platform "A":
Union Station to North Hollywood
Union Station to Westwood
San Pedro to North Hollywood
San Pedro to Westwood
Lower Platform "A"
North Hollywood to Union Station
North Hollywood to San Pedro
Westwood to Union Station
Westwood to San Pedro
