Don't try and reinvent the wheel bro, your on a real solid program, and hopefully it's worked well. If your ready to move to somthing different, try and find another program that suits your goals. I personaly don't like jump[ing from one program to another, better to let your program grow with you, as your body, and knowlage gets bigger.
"Evolution not revolution", so with the program your on you press 3x a week, probably day 1 bench--day2 incline--day 3 military, all 5x5, somthing like this I asume. So when your done with your 5x5 pressing drop the weight, and add in some tri's. On bench day, 3-4 sets of close grips seems easy, On incline day, 3-4 sets of incline skull crushers, after your pressing, and on military day you could do french press, but this is where I'd put dips (military, and dips work well togeather) somthing like this wouldn't tax your recovery or time frame, and will add growth to your tri's, a couple sets, before the next exercise.
The point is this is how training evolves, you have a goal, and make ajustments to your current routine to find the most efficant means to reach your goals, with out "A" adding to much volume, and "B" completly reinventing your program every time an idea pops in your head. goodluck
