My personal experience--I started out on Case backhoes, with 3 stick Case controls. Then I bought a Case 580 that had JD type wobble sticks. It took a bit before I got comfortable, but I could jump from one to the other and back seamlessly. (With this exception--running the 680 backhoe, the hand throttle is there by your left knee, and on the 580 it was next to the steering wheel. No matter which machine I got on, I was always grabbing for the throttle in the wrong place. I still don't know why.)
Anyway, one day I got on an excavator, and it was some trouble to get my hands to learn excavator pattern, but once I did, I could still move from an excavator to the 580 to the 680, and not have any trouble with any of them.
Those Case machines are long gone. Now, if you switch the pattern from excavator to the JD backhoe pattern, I'm totally befuddled for an hour or two, and then I start to get ok. It takes a while longer to actually get competent. Now, if I get on a backhoe, it also has to be excavator pattern. I've lost the ability to run a backhoe with the other pattern.
As long as you can switch patterns on the machine itself, so somebody else can run it, I'd leave the muscle memory in my hands alone.
