you are worried that someone else will bring scouts in 500 points? seems unlikely, maybe the plaque of tepok would be better even tough its 5 extra points otherwise i just suggest changing at least some of the cohort to skirmishers as without korxigors they can't even get a draw in combat unless you are really lucky when you charge and if they get charged even skaven slaves are going to eat them alive
