The market is anonymous, unless you and our 'friend' agree on which product to trade you have no way of identifying the other party. On popular products, i.e. Google or Apple, this is impossible. On other products liquidity (trade volume) is so small that such transactions would stick out like a sore thumb.
On top of that, it will take a lot more than two lines of code to defeat all the checks and balances in trading code. These checks and balances usually trace their origin to things having gone wrong in the past. I would expect all trading firms to have good source code management systems, your 'enhancement' will not go unnoticed.
