Advice: Big Sur + Sequoia + Joshua Tree?

Hello! I'm eloping in Big Sur this coming September. We've landed on a honeymoon in Joshua Tree. It's our first time in California, and we'd love to see the Sequoia National Park after leaving Big Sur (going south to Cambria area and cutting east) Is it too ambitious? The ride from Sequoia to Joshua Tree has lots of good stops, but is it too much for one trip? Is there any interesting path from Cambria to Sequoia? Two weeks total, 4 days in Big Sur, 3 days in Sequoia, 6 in JT. Thanks!
