Kyoryujin's legs don't need to accommodate ZB, though.
But I don't think they could even pull it off, anyway. The requirement of having the batteries be the connection point just makes it a tad impossible to make it ZB compatible.

Yeah, but BoA would still probably make the attempt.

And I was referring to turning GabuTyra's neck and tail joints into ZB pegs, not the battery connectors.

They could just stick Zord Connectors on the Beast Batteries

Even if the individual zords look bad due to connectors being mounted on them, that won't matter to me if the combined Megazord looks good.

As much as I would love to see articulation...it probably won't happen anytime soon for two reaons, because of Sentai tradition, it's the same reaon why Lego minifigs haven't changed much at all. Second reason being Sentai mechs and Megazords are all about their gimmicks and not about articulation (or lack thereof).

Yeah, this right here. I also cringe when people suggest more articulation for Lego minifigs, it just won't look right!
