Great. Thanks for taking the time to do that; much appreciated!
Why would I want to interchange them? Well, basically because the cockpit tunnel ridge on the 144 TFA/TLJ model is just awful. The trough is too wide and is filled with random greeblies that don't look anything like either the 5 foot OT Falcon or the TFA/TLJ movie Falcon. It's a source of great mystery to me why Bandai did such a fantastic job on modelling the ship in most every other regard, yet mess that up so badly! They did almost exactly the same thing on the 1:350 version of the ship, weirdly.
I've made a 3D printed replacement ridge, but it's a huge pain to install as you have to get the scribings to match, and that's hard to do well. So I'd almost buy a Lando Falcon just to get a better fitting part. But they're too different for that to work. Ah well.

You're welcome! I see why you would want to now... I know how difficult it can be to put your corrected piece in there. I did it on the 1/350 falcon and that was challenge! But yeah, they are to dissimilar to make it work.
