If the Beta Rangers had their own Battlizers, they would be based on Legendary Battlizers. As you can see, Devon's temporary Battlizer was Red Fury Mode and never seen again in the series.

If Hasbro could just bring back the Battlizer morphers, the Beta Rangers would have a different version of various armors than the original. For instance, some allies might fuse with them to create combative armor.

White Ranger - Timberwolf Snow Armor (Snow Prince)

Pink Ranger - Pink Savage Warrior (Animarium Buckle)

Aqua Ranger - Aqua Armored Ranger (Galactic Key)

Purple Ranger - Purple Battle Warrior (Battle Fire)

Black Ranger - Black Mega Battle (Battle Booster)

King Ranger - Solaris King Ranger (Jenji)
