I was thinking, when you add new fish your always get a nitrogen spike, due to excess ammonia and not enough bacteria in your tank to take care of it. I was thinking there might be a way to help the mini cycle, theoretically, a few water changes before you add new fish, what if you slowly weened down the amount of water/gravel you siphoned per water change? A little extra debris (slowly built up) would cause more bacteria to grow and break it down, if you did it slowly there wouldn't be much of a spike. When you are ready to add the fish you can do a large water change, but you would have more bacteria built up to help process the new fish. What do you guys think, would it work?
