I know what you mean. I solved the issue with a specially designed adjustable linkage on the Lagrange (https://github.com/dpapavas/lagrange-keyboard https://github.com/dpapavas/lagrange-keyboard). It took a while to finetune the relative position anf attitude (which, turned out to be what one'd expect: 0° toe, separation at about shoulder width), but now it's finally consistently aligned every time. (The palm keys also help by doubling as guides to keep your hands in the right place.)
