Or if you want a quick flight than just take Qatar.
I would be very careful with the SEA-ICN flight. I have tried SEA-ICN-KUL a few times and SEA-ICN tends to be delayed because of weight and balance issues. (Not sure why?). Google flights has bad on time stats for this flight too. This means that a lot of passengers misconnect in ICN. They have moved the SEA-ICN to be earlier at least from September: that leaves more time making for a still risky connection.
Also, ANA has started a new NRT-KUL flight. You're not getting MQMs for the KE flight anyway so I would consider the NH option as well. Main drawback for this is the regional configuration on the NH aircraft. Still the same excellent NH crew though.
I sometimes connect in SIN as well to KUL but that always requires an overnight stay. You could maximize your MQMs by getting on DL to SIN and then taking the 6am flight out the next day.
