Thanks a lot for your input!
Yes, the cables i used were cut from a 800Amp jump start package which has very thick gauge wire and thick protection layer that I believe can handle 400A transfer well.
The kill switch actually is called SCA Battery Master Switch which was rated 250A by trade. I found that it has a very solid design, and based on my experience with kill switch then 250A rate is very accurate if not more.
Following your idea, I just did a test of 5 times cranking the engine on continuously. After 1st to 3rd times the terminals of the kill switch are very cool like nothing change. Only at 5th times then I feel a slight change of temperature which might be just about few degree. So it seems it works quite well for now.
Also the cables feel completely cool.
I will keep an eye on it often, but at least I can drive the Disco quickly now after a day off the roads.

(especially true for me who would not want to take the challenge to remove the starter motor out).
