you guys should make a robot that plays with metrics.
put one in the cloud and train it with open source (or even private data) then sell the trainig data (or provide it free, for all i care)
train it with metrics that are simple (like total lines of code), evaluate it with number of bugs (or technical debt or both or both and more) and let it give recommendation for metrics that are "shallow" (like polimorphism factor ; where the value can be many things and the project can still do good)
