Thought we could do with one for Chinooks, but might as well expand it to Sea Knights, Belvederes, Yak-24s etc..., so here you go, a place for all your twin egg-whisk ideas. :)
What prompted me were a couple of things that led to a couple more things:
1. Has there ever been a proposal for a skinny-fuselage flying crane version of the Chook, a la CH-54 Tarhe? if not, then this is something whiffdom could recify.....
EDIT: yes there was - see here: http://www.secretprojects.co.uk/forum/index.php/topic,565.15.html (http://www.secretprojects.co.uk/forum/index.php/topic,565.15.html)
2. Whilst looking up point 1, I found this, which looks very doable:

from here: [url]http://aviationtrivia.blogspot.co.uk/2009/11/first-flying-on-27-may-1970-boeing.html[/url] ([url]http://aviationtrivia.blogspot.co.uk/2009/11/first-flying-on-27-may-1970-boeing.html[/url])
First flying on 27 May 1970, the Boeing Vertol 347 testbed was a modified CH-47A Chinook (aircraft 65-07992) used for Boeing's HLH (Heavy Lift Helicopter) program. The helicopter featured just over 9 foot extension of the forward fuselage cabin, a raised aft rotor pylon, four bladed rotors that were two feet longer than a standard Chinook blade, fly-by-wire controls and retractable landing gear.
But the most unique feature of the Model 347 was a variable-incidence wing that created extra lift to offload the main rotors. There was also a retractable gondola in the forward fuselage that had a full set of flying controls during flying crane operations. As the twin rotors no longer overlapped, some degree of noise reduction was also achieved. The Model 347's performance was greater than that of the standard Chinook, but flight testing ended in 1975 with the cancellation of the HLH program.

Nice one Jon.
There was a pretty Saunders Roe Project called the P514 Rotorcoach that had a low-mounted wing amidships and a ducted fan behind the aft rotor pylon: I don't suppose you have a 3-view of that do you?

Re the ACH-46, I was actually toying with stealing the cockpit/canopies + stub wings from either a Cobra or Hind-D.

I'm thinking the cockpit/canopy from a Hind-A might work better, or at least serve as an inspiration (trying to fit it to a CH-53E showed the difference in fuselage depth to be pronounced, even in 1/72).
-
Maybe if you were to raise the CH-47 cockpit upwards slightly, then graft on a OV-1 Mohawk cockpit in front and below of it ---
Adding turrets and such would be relatively easy I think.

I see it has a white painted roof like some RAF ones, what was the purpose for painting it that way ?
-
Reflecting / reducing the absorption of solar generated heat? Note the RAF used white paint on top extensively for middle east and desert based A/C.

Yep, which is the same reason post-WWII airliners were/are primarily white or bare metal.

I wonder if they have a Bell HSL to go with all those other tandem rotor helicopters. It wasn't that successful and I doubt there are many, if any, left.

Cool.

But it needs a 3 bladed rotor. The two blades looks unusual.

In 1976, Boeing Vertol teamed up with Bell's Helicopter Division on a proposal for the Army's PLR (Power Lift Rotorcraft) program.
Designated XV-16A in the VTOL series, this clean-looking and able performer combined Boeing's experience with transport helicopters and Bell's expertise in VTOL, in this case capitalizing on the tilt-duct research that culminated in the highly successful X-22A prototype a decade before.
The PLR program was canceled despite a successful two-year evaluation phase because it was found that its advantages did not outweigh the 35% increase in costs from operating it instead of a conventional Chinook.

During planning for the Escort Cruiser by the RN, it was postulated that the an ASW version of the Chinook would be developed to make use of the extra deck space.
I know about the ships but haven't seen anything on the Chook version. Earlier versions of the Escort Cruiser concept mentioned an ASW Belvedere.
-
If there was an ASW version of the Chinook, it would likely borrow from any ASW work done with the CH-46, it's smaller sibling.
-
The enlarged sponsons with increased fuel tankage of the 234LR would a better way
to increase range.

Finally... 10 years after the withdrawal of the last heavy transport helicopter of french armed forces (SA-321G Super Frelon of French Navy), a new one might come before 2025 to fill this gap :-*

The first one is the Boeing-Vertol Model 107 aka CH-46 "Sky Night", not the Model 114 CH-47 "Chinook".
The Model 107 and 107-II were used in the airliner role.
The Model 234 is the civil variant of the Chinook, and they were operated by British Airways.
