I succumbed yesterday to Mr Galli's whole plate temptress.

Doing a little bit of research over at the Large Format forum, I think the Korona takes Eastman-type holders, so the Rittrecks might be 3mm too long.

But after three attempts at whole plate, I have come to believe that "nobody knows nothing" when it comes to whole plate. I have found conventional wisdom highly suspect.

So the best answer is, wait until everything's in hand and give it a try.
