Pretre-whose going to say no to proxying when we're playing DARTBOARD 40K. It's by its definition, for fun.
It really isnt complicated and the model collection required, while probably not small, doesnt need to be gargantuan. You have to roll for each FOC slot, complete the unit and move on to the next.
So here's an example, When you get a chance, go through the Marine Codex and use these randomly generated Numbers. Build each unit (no cheating) and then then move on to the next one. When you get to 1500 points, stop building. This is just one example. I don't even have the Codex in front of me so i have no idea what this would make. But your opponent gets similar random numbers and then you build it the best you can with the models you have. Show up with your list and play.
Fun. Someone tell me what this would look like. I'm kinda curious myself. If someone wouldn't mind telling me what this produces for, say, Tau Empire, or Tyranids that would be cool too. or whatever army.
Then you play, flip armies, play again and yer done. Good times!
