It's one of the top links when you google Kirk's name. I just glanced at it, but it's four days with each day dedicated to one of the big four. Regardless, I don't know what there is to combine: 5/3/1 basically is all about heavy, compound movements and the Wendler Six are the only assistance (accessory? I get those mixed up) movements he recommends. You really can't get much more old school (or simple) than this. As for Kirk, the description there isn't very specific... not specific enough to follow, for sure.
I also noticed, after more reading, that (true or not), an apocryphal story has developed on message boards and other posts that Kirk never missed a rep while working out. This is more important in terms of mimicking Kirk than is his workout split. Whether the story is true or not, the lesson is that the guy was so intense and so committed to the goal that people around him respected him enough to develop the legend. If you're that intense and you have a program that works, you'll make strides. I don't know that you'll be that thick, but you'll be thicker than you are now.
Another piece of advice I've picked up from people far more knowledgeable about lifting than I am: don't mix programs.
