Absolutely a no-go. Any sort of a delay and the connection will be missed. No room for error on a connection like that. Taxi delays, weather delays, and the likelihood you will have to take the train from A/B to S for the HND flight all do not bode well. I’d find an alternative flight and get DL to switch it for you. My rule of thumb in SEA is not less than 1 hour if there are multiple flights left to my destination, and no less than 1 hr 30 if it’s the only flight.
