I wish editing was as simple as copy/paste so I could just blend the scene in myself. But I totally understand if you want to keep it the way it is. But yeah please, no need to touch Space Leia. Your version is fantastic at moment (in my opinion).
This might not be impossible using MKVToolNix - you’d have to remux each one and split it at an equivalent point just after the Hux convo, then use the "join* feature to cut in the first part of Hal’s with the rest of poppa’s.
I actually kind of agree with you, so I might experiment with trying this out when I have time and see if it works. If it does, I’ll provide detailed instructions.
Probably couldn’t play it on everything depending on the encoding settings of the two edits (which might preclude this from being doable at all without reencoding first at equivalent settings), but it should work on PC software players like MPC-HC.
