I doubt that very much Vin.
I know that things are DIRE and that 2 fleets per role is the aspiration from on high, but I cannot see the Herc J Fleet getting dumped post SDSR (The K's are another story, obviously). More likely I would suggest is that we're talking C-17 and Herc J until 2015-16, then sell the J's and get take delivery of A400M.
I didn't say it was a sensible plan though
