Incredicoaster & Guardians are in the top 3 rides at DCA and most definitely should be included!
I would however, skip: Goofy’s Sky School, Silly Symphony Swings, Golden Zephyr and Jumpin Jellyfish because even though they are unique to DCA vs. WDW, there is nothing about them that makes them unique from other theme park rides of the same variety (their Disney theming is very light/non-existent). The same argument could be made for the Pixar Pal Around but that one is a family favorite for the views you get of Disneyland and DCA (some of them revealing backstage areas so be warned).
Also in DCA, I would only do the following if time allows as they are all available in almost identical formats in WDW (and in some cases, better): Toy Story Midway Mania, Little Mermaid: Ariel’s Undersea Adventure, (both of the above having better theming of their queues at WDW and the rides are identical), Turtle Talk with Crush, Mickey’s PhilharMagic, and Disney Jr. Dance Party.
In DL you’re absolutely right it would be wrong not to go into the original park being steps away and your choices to do Matterhorn, Indy & Pirates are great. I would also be sure to add Space Mountain (a much smoother experience and different ride vehicle than WDW’s version).
Also for me personally no trip to capture the flavor of Disneyland would be complete without: Disneyland Railroad, Storybook Land Canal Boats, Alice in Wonderland, Mr. Toad’s Wild Ride, Big Thunder Mountain (WDW’s version is a little more intense, but the effects & scenery at DL are usually rated as better compared to WDW’s) and it’s a small world (it’s vastly different between the 2 coasts so recommended to do on both but Disneyland’s is strongly considered the better so very much consider doing it as well).
If time, the following give you such a good sense of Disneyland that they should also be considered (but I get that a day is a short so only if time): a trip around the Rivers of America on one of the 3 attractions that make the trip: Mark Twain Riverboat, Sailing Ship Columbia or Davy Crockett’s canoes (you paddle the canoe yourself & it’s SO much more fun than you would think reading that sentence mostly because the guides are funnier than the funniest Jungle Cruise skippers), Mickey & Minnie’s houses in ToonTown, Pixie Hollow if you have a Tinkerbell fan, Royal Hall if you have a princess fan (you get 2-3 princesses with the one wait and the interactions here are top-notch & even though we do it nearly every trip I never don’t leave with an absolute huge grin on my face and a so happy I could float away feeling). The daytime shows in Disneyland are also so wonderful: Mickey & the Magical Map and Storytelling at the Royal Theater so also highly recommend if time. The Carousel, teacups and Dumbo are also all musts for our family (all are similar in WDW) but they are unique enough in DL especially since the views are different that I wouldn’t discount them as the same ride.
Lastly, I would be remiss to not mention Great Moments with Mr. Lincoln and the Disney Gallery before it that showcases some wonderful Disneyland history including one of the Griffith Park park benches (where Walt dreamt up the idea of Disneyland) as well as the Disneyland Fire Station (the 2nd story holds Walt’s apartment and in the window is a lamp that is always lit- when he was alive the lamp was lit anytime he was inside the parks & following his death, the lamp has remained almost continuously lit to represent his presence has never left the parks).
So in short, is there anyway you can add a day?!?!? 
Maybe even 1 park per day?? And limit dining to snacks/packed lunches? Also if I only had one day for both I wouldn’t do any table service meals to save the time for more things. There are so many good snacks/counter service meals that are a better use of time than any table service meals, especially in DCA.
Anywho, sorry to ramble on & on but any other specific questions you have about your day & your plan, please ask!
