The replacement for the Royal Air Force C-130J's

Yes folks the powers that be have once again decided to retire the whole of the Royal Air Force's C-130J  Hercules fleet and replace them with the larger Airbus A400M Atlas. This will cause a gap in Transport Command as they are bound to want something smaller than the Atlas,  along with STOL capabilities.
To a Whiffer this means something commercial although it could be turboprop or turbofaned or even a combination of the two. So something smaller than the Atlas but bigger than the BAe -146.
The thought of a four engined C-160 has been on my mind for quite a while and the Roden An-12 Cub kit although not the best model in 1/72 scale does have potential to be whiffed.
I'm sure more ideas will follow.

if they are looking for something smaller then an A400M, inthe same league as the BAe146, then the RAF should either go with the Airbus C295M or the Lockheed/Leonardo C-27J Spartan.
on the bench:

-all kinds of things.

Would the venerable Beverley fill the bill?  Take off 750 yards, landing 300 yards (both approx)  max load 22 tons, ferry range 4000miles

For comparison  Andover T/O 650 yards, Landing 350 yards    max load  7 tons, ferry range 1500 miles

Of COURSE a Bev would fit the bill, but you'd re-generate the 'Crew Generation' problem.

That's the one where you have to sing on a complete family (or three...) for each crew to ensure there are enough qualified pilots still alive to land the thing at the end of any long range flight............

Oh, I dunno - seems to me a turboprop upgrade should speed things along quite well.  And, they could use all those suddenly surplus C-130J engines - RR engines, IIRC.  :)

They could, but then the more than doubled speed might yank the landing gear off, and then they'd need to make them retract and then you've got a whole 'new' aeroplane.......

I would have thought that a re-engined Argosy would be more appropriate.  I suppose that the C-27 could be lengthened if needed or the Kawasaki C1 which has been offered to Australia. Then there's the An-72/74 which could find its way to replace the BAe 146 or the C-390 another twin turbofaned,  Hercules size aircraft.

Isn't it time to rebuild the Short Belfast? Or a smaller version called the Shorts Derry?
