[Converting old world rules to AoS]

Anyone attempt to convert some old world rules to AoS for narrative games just to change things up? For example, I know a while back someone brought the Wizard cast to fail chart up to date with Sigmar. I'm looking for more stuff like that, maybe artifacts, weapons, Armor, Spells, I was thinking about trying to do some chaos stuff from the Realms of Chaos books for my Nurgle.

For the ability  Summon Imperial Guard or summon Men-at-Arms is it still once per game per Abhorrant or is it gated only by command point availability, For example, if I have 1 command point per turn could, I use either ability with the same King each turn for 5 times total in a game?

Question for you folks, do Pestiliens benefit from the Cycle of Corruption at all? since they are nurgle keyworded or it is for maggotkin and daemons of nurgle only.
