If the idea does not make sense before you do it, it probably won't make more sense afterwards ...

But you'll have a correlation matrix by individual, and that will show you pairs of individuals whose measures on the different variables tend to correlate more or less strongly. I can't help a suspicion that something like PCA might help more than a raw correlation matrix, if you want to see how closely individuals are associated, but correlation is a possible step on the way.
