It's kind of obvious, but, from what I see:

Super Megaforce - Gokaiger 1

Earth Fights Back - Gokaiger 5

Blue Saber Saga - Gokaiger 4

A Lion's Alliance - Gokaiger 9

Samurai Surprise - Gokaiger 11/12

Spirit of the Tiger - Gokaiger 7

Silver Lining, Part 1 - Gokaiger 17

Silver Lining, Part 2 - Gokaiger 18

Power of Six - Gokaiger 19

The Perfect Storm - Unknown

Love Is In the Air - Gokaiger 14

United as One - Gokaiger 29

The Grass is Always Greener or Bluer - Gokaiger 27

In the Driver's Seat - Gokaiger 35/36

All Hail Prince Vekar - Gokaiger 37/38

Including Legendary Battle, that's 16 episodes, with 4 missing, which are likely the Gokaiger 40's episodes, like the Timeranger, Megaranger and Kakuranger episodes as well as the Basco episodes. They also skipped a lot of 20's episodes, like the Boukenger, Hurricanger, and GoGoV tributes.

There's also the Ohranger tribute if they want to use Basco's monster form. I want to think The Perfect Storm will use Gokaiger 32 to introduce the Galleon Buster.

Also, we have to keep in mind any possible episodes near the end dedicated to using Goseiger footage of Vrak's final form/Brajira.
