No matter what X and Y are, that's just the wrong way to solve that problem.
I don't know, If I can't do Y how am I going to hire an A player at the Y game. Being good at X means I can evaluate others in skill X.

You do X, hire Y - You have one skilled person, one question mark.

Seems pretty simple to me that the first is better. I suppose that you could make the argument that Y may be easy to pick up, but if that's the case it should be all the easier to just hire someone else with a proven track record.
