It is valid to think that this case could be possible, but it is only possible. I still have to understand/comprehend/grasp what is the exact political alignement of Jamyl. It's quite obscure. Considering that the past centuries have seen drastic changes in imperial citizens morals, ethics, mindset, and faith to the point it does not look like the old Empire anymore, I have difficulties to see the real influence Jamyl (short reign for now since she is very new to the throne) has on the Amarr society. Especially since her policies are obscure to me. Anyway, it would take more than a few years to reverse what Heideran has done over centuries.
It is funny however to see Caldari patriots afraid of the past actions of other Empires when their own current actions threaten the rest of the cluster (<- that's not a neutral pov, mostly Lyn's).
