I think this hits the nail on the head.
That said, it also seems like low hanging fruit. At least in some fields, replication should be a lot cheaper than doing things in the first place -- because a lot of the cost in pissing about trying to find something that even seems to work.
For funding bodies to explicitly support replication studies, even if each gets only 20% of the amount the original studies get should be a winner at reasonably low cost.
