A King can never stop two Pawns that are separated by more than 1 empty file.No matter whether it is in the square of both. Not even on a 4x4 board. This is related to the point whether a King would be more frequently on its own half. Often it will be behind a single Pawn, because it needed to go there to capture another Pawn when there still were two.
As to larger boards: Kings will be weaker, but other leapers will be as well. It has not been investigated whether their relative values change. They will certainly go down in value compared to sliders. It would be very interesting to measure values of the orthodox Chess pieces K, N, B, R and all their compounds on 10x10 and 12x12 boards. Perhaps one of these days I will be able to find time for that.
