Ultimately, even if you ignore FreeBSDs and OpenBSDs history of cooperation (or the lack thereof, either of which I won't get into), the projects have different values that don't necessarily mix - so I'm not sure it's possible. It's okay to have different values, we don't all need to think a certain way.

Personally, I'd also begin worrying about mono-cultures and a lack of competition, if they were to be forced together. In the market-place of ideas, it's good to have multiple approaches to a single problem, because it lets you shop around, evaluate, and pick whatever solution fits you and your requirements best.
