My first thought was; damn, you could fit a lot of Carlo Rossi jugs in there, but yeah I think you best bet it bending the shelves. running it horizontally may not work so well due to how the condenser is set up (it might do fine too, just sayin', I don't know). Have you sized out how many shelves you would need to bend? It looks like you would only have to bend two, and only to a 45degree angle or so to clear the shoulder of a carrboy.
A close up pic of the shelf/coil connection would make it easier for me to say that this is worth trying or not
