Not sure if this answer suffice, but relating to logical fallacies when considering multiple gods, there can never be such thing as 2 perfect necessary beings. Why? Because 2 things can't be perfect because they observe the same qualities of perfection, ergo that collapses to just being 1 being. If you had any differentiations that would mean at least one possesses an inferior quality and therefore not perfect.
I am saying this to show that it's impossible for a perfect being to arise from another perfect being, so we can cut that branch of for this discussion.
if you subscribe to absolute divine theory, then we can rule out any interpretation of "imperfect arising from perfection" being that a piece of imperfection was taken out of perfection, since God is indivisible.
I hope this can help
note: I can't recall the fallacy with there being 2 non-perfect gods, but that's not relative for this discussion. If you're interested LMK
