No one can tell you what material to do, it's all on you and what feels right for you. While you might get ideas from these guys this is how it works in reality.
I'd suggest that you define a persona first, that's where you'll be able to create that "quality" you're asking for. Study video of the old timers and the simple routines they would do that brought down the house; most anything by Billy McComb or Ron Wilson will be great examples for learning what I mean. Dresscode is a great opener I'm not familiar with the other two by name but the question you need to ask is how do they fit as part of your storyline? Do things naturally flow together or are you simply showing off your favorite tricks?
Why not material that allows you to put other frat members on the spot, like Paper Wads Over the shoulder? or Pick-Pocket work?
These are just ideas for the sake of production value.
I wouldn't do a Smash & Stab routine for a couple of reasons, the biggest being that Frat boys + Booze = likely disaster when it comes to something so potentially dangerous but, there are variations to the roulette effect that are far safer and more entertaining.
Just a few things to think over.
