Startup Idea : Cofounder search by personality traits

It's always about the same thing, you want to find a cofounder and there are plenty of websites to help you find him according to skills (PHP...), hours per week and money to contribute.. However, I would like to find a cofounder with personality traits I like, for example: what's your vision to the future, are you short term or long term person, do you prefer marriage or to be single .. according to me, much better results to be found.
