This is probably as close as you will get. As for "ergonomic," that is almost as abused a term as "organic."
A simple fix to make any keyboard more comfortable and less irritating to the wrist is to change the conventional angle of attack. Consider the concert pianist - it is important to keep the wrist level and not flexed like this . . . \-/. Better like this /-\.
To achieve that, raise the front of the keyboatd higher than the rear, and use a wrist rest pad so that the angle of attack is downward.
Unfortunately, most OEMs put the foldable legs in the rear, and they really belong in the front for best ergonomics. The keyboard should slope away from you, not tilt up towards you. That is a bad design inherited from old typewriters.
What I do is place a small board under the front edge to tilt the keyboard slightly away. That board can be easily fixed with velcro. Some desks have keyboard trays that can be tilted away from the user. That's good.
