If it was me....
I would change the SoCal route completely. PCH and HWY1 sucks once you hit Long Beach and head North. I would go Rt74 in San Juan Capistrano to Elsinore, have a meal at the Lookout, then up Rt 15 past Ontario, CA to HWY2 West. This is the Angeles Crest HWY and eventually you end up north of LA. near Rt 5/118. Then head due west back towards the coast and back to the coastal beauty all the way to NorCal. It will take longer but so what, at least you will be moving and seeing the mountains, some high desert and then the coast.
