That would have been cool.

I remember thinking before Super Megaforce came out after hearing that they refilmed the Legend War to remove the Pre Zyuranger Sentai Rangers that it would have been cool if they still used those episodes but refilmed them to have the other Saban superheroes.

There's also Super Hero War Z. That has Shaider, and Kamen Rider Black RX, and the Gokaiger morph into Blue Stinger Borg, Chromium Gold Borg, and Karato.
