I've thought about taking this approach but after being at my current job for 7 years I have made certain observations about my boss. My boss holds grudges and frankly I don't trust my boss (but that's another issue for another day). This is a very small project and would not make a dent on our bottom line but I cant help but think my boss would see this as betrayal.
