Well you can't really say they wouldn't look good together. I bet the only thing stopping more people from shipping them is that they are suppose to be father and daughter, but in the manga world anything can happen. I personally feel that it could go that way at least for Caitel (not sure about Ariadna) because he seems a little to attached to her.

A broken sword huh, poor Dranste...
And please don't be angry but I'm shipping Caitel x Ariadna...
I know... I'm a horrible person... I'm a sinner...
I'M SORRY!
