Sat down to examine my Trek Library. If the episodes were bundled together like this for a theatrical release, IMAX, 4K whatever. I'd pay to see these on the big screen. A lot of the early season multipart stories work well for theater experiences.
TOS - Amok Time and Doomsday Machine
TOS & ENT - Mirror, Mirror and In A Mirror, Darkly
TNG - Q Who and Best of Both Worlds
TNG - Yesterday's Enterprise and Sins of the Father
TNG - Reunion and Redemption
DS9 - The Jem'Hadar and The Search
DS9 - Way of the Warrior and Apocalypse Rising
VOY - Scorpion and Year of Hell
VOY - Drone and Dark Frontier
ENT - Broken Bow and The Expanse
ENT - The Xindi, Azati Prime and Damage
ENT - The Council, Countdown and Zero Hour
ENT - Demons and Terra Prime
If episodes are going to be mixed and matched in order to be bundled together, then that opens up more possibilities.
