I have to say that Witchbrew is a much better choice than manbane for the hags... as witchbrew negets most enemy CR bonuses.
For making your warriors more durable remove one CoK and the Dread Knight (as he costs plenty of pts and only gives one extra attack) and give all your warriors shields.
I suppose you'll give the executioners a 4x4 formation cause your general will be in it too? if not you can remove one executioner as well.
Without magic you'll suffer bad if you opponent have some good potentioal in magic so IMO a unit of harpies will help you more than the CoK unit. Like a unit of 10 harpies will only cost 130pts and are excellent mage killers. Ofcause you'll loose the only unit that hits hard at I order... but I seriously think that you're better of with the harpies if you face a army with 2 or more mages. If you take the harpies you can increase the numbers on you warriors as well to 20 and 16 an your non rxb units. But then ofcasue if you face a hard non magic army you'll be better of with your knights
