No, because then you have to lift a large weight, it is easier to lift two or three smaller weights, especially when leaning over to reach to the back of the van. Actually, it is easier to lift one small weight, which is why I suspect any future such arrangement will include a stipulation that each rider can carry all their luggage on their bike. Because at some point that will happen. And is why I have bought some Ortlieb front panniers: small, waterproof and they fit on the audax bike rear rack. That bike wobbles terribly when carrying two large rear panniers, a large Ortlieb kitbag with camping kit, while the rider wears a large rucksack with more camping kit. I know this.
