As for Hera, hmmm… I’d be a bit careful. Despite not being all that strong in a straight fight and not really controlling a, on the surface, weak domain, one of her big domains is marriage so…. I’d be a bit wary. It is also a bit conflicting as one could argue that at least 2/3’s of her actions throughout history could be blamed on Zeus. I’m pretty sure she rebelled against him at least once in the past which is supposed to explain why Zeus has a tendency for paranoia when it comes to his family.
How exactly would Hestia be a threat since Layla has the Mana Burst and the Rinnegan techniques, besides even if she somehow becomes a threat Layla could resort to using the Limbo to finish her off but now that I think about it what exactly is the Rinnegan that Layla carries? because if it is Madara’s in theory Layla should be able to use the Limbo.
