Still, I think that they would have done it. I think i read somewhere that part of their initial plan was to land troops in Hawaii, but i can not recall why they would do so.

You are right that their supplies would be stretched, but the US would have had a hard time trying to retake the Islands and Midway. Its out of range of most bombers and fighters from the early part of the war (in relation to the West Coast of the US) and skipping over Midway would cut its supplies off. I think a token naval force along with a division of Infantry in Hawaii would have been able to last long enough for the Japanese to consolidate its forces and the other Islands and be in a better situation than it was historically.
