I think it's probably a little ambitious... esp considering the distances involved. My choices on your list would probably be something like this:
Disney Concert Hall
Griffith Observatory
Universal Studios
Hollywood Bowl
Getty Center
Tide Pools
Disneyland
Santa Monica Pier
Santa Monica Beach/Shopping
add in The The Tar Tar Pits and the Peterson Automotive museum, and you're set. Maybe add in the Natural History Museum, 'cause who doesn't want to see a 30 foot long partially decayed fish preserved in alcohol?
