I think Goseiger could have made a great anniversary season, it has lots of callbacks through the franchise, lots of "back to basic elements" but it also had a great gimmick set - the cards and the headders - and the general design of the suits gave this regal anniversary feel. Best of all though is Goseiger had a boatload of villains and INCREDIBLE action, so there is lots of easily usable footage.

In terms of plot? Kickback's Dino Charge idea of descendants would have worked pretty great, I think given the designs of the suits and stuff. Tying the villains back to the original villains the Rangers who are descended from to as well for world buildings sake would be pretty fun. Then the Super Mode could be the result of the powers of the past, and the Ranger of the present unifying.

Then at the end when Brajira comes back, the Megaforce Rangers stand side by side with whoever they are descended from for one final Mega Battle.
