That's the image I saw on the website.
As to replacing the tension lock, there are problems with what we as users would want as there will be conflicting requirements.
I know I want an unobtrusive, DCC-controlled coupler suitable for finescale OO operation with eased out back-to-backs on +28 inch radii curves, where having a bar to push against for propelling over pointwork isn't required (the buffers do their job without override). Too wit, I have in mind a modified AJ-style coupler controlled by, possibly, a Preci motor unit otherwise used for Kadees. The issue there is the motor won't return a non-sprung coupling to a resting position, so I'd have to add springing in situations where the AJ-style wire is too short to be self-sprung.
I'm absolutely sure that's not what most users want, as the lack of bar for propelling on set track tight curves would be a non-starter.
Edit: also, I'd want the coupler to be body mounted. Couplers on bogies are a no-no for me as it prevents detailing on buffer beams and puts the wrong stresses on the train as a whole. Of course, with what I've outlined above as minimum radii, close coupling mechanisms just aren't needed.
