Harder difficulties for the blizzard campaigns

Well I just beat the game (again) and I was wondering if there was a way to make a mod that made the game have difficulty levels harder than hard mode.

I thought maybe going into the mpq and adding triggers for a harder mode might work but that wouldn't work because there's only a normal and hard mode option on the campaign selection screen.

Does anyone know how this might be done or maybe if there's an already existing mod that does so?

P.S. If this is in the wrong forum, I'm sorry. I couldn't think of anywhere else where it might go.

EDIT: If this is impossible, please say so.

it is the right forum. I don't think you can go any harder

you would have to code everything. To select the modified difficulty, display a dialog at the first map, if the difficulty is hard, to select the even harder version.

limit yourself to only having 4 worker units at a time, max

that should equal about... uber hard?
