Good call on the washers, I've never put them in a KA head but we use them in the 4G63 platform.

I wouldn't necessarily say so, m12s would require machining done to the head to be able to torque the fastener, unless someone create some sort of custom nut to allow use of smaller socket. Not needed with m11s, and with l19/ca625, you'll still get comparable clamping loads which probably sufficient for 95% of builds.

The idea of using a bigger headstud in KA has kicked around for awhile. Dsport had wrote an article about using timeserts for a bigger stud in KAs, but i'm sure they probably got the idea from somewhere else as well, they just brought it to light. Duncan351 documented the use of insert washers with the KA.
