You really need a unit of Ironfang Pikemen, as both are very good with bot Irusk's. Right now, you've got the army for a decent pIrusk list at 35 points.

Kommandant Irusk
* Behemoth
Great Bears of Gallowswood
Kayazy Eliminators (Leader and Grunt)
Widowmakers (Leader and 3 Grunts)
Winter Guard Infantry (Leader and 9 Grunts)
* Winter Guard Infantry Officer & Standard
* 3 Winter Guard Infantry Rocketeers
Winter Guard Mortar Crew (Leader and Grunt)

pIrusk is better with what you have going. E usually is better in 50+point games imo and i run e with mow only and a jack. Pirusk is a great starting caster imo next to butcher. (vlads ok i guess but boreing) he is really the only caster i take only one jack with usually behemoth torch or ivan. Or i just go frugal and bring a breserker. Irusk1 has a great toolbox of spells with our (in)famous Iron flesh, and battle lust on the great bears is really painfull they can wreck heavys on charges rolling 5d6 on dam. Then air burst is great for stealth because the target can only be barely in the controll and still be a valid target. Sylus really helps him out but his teir list is pretty appealing too just take a wardog. Units he likes are the usual suspects. But iron fangs shine with him for battle lust and iron flesh. His last spell grind is situational but i like to use it to knock off that last m box on cryx and cygnar lights to make them less jumpy pirusk dosent do much for mow

oh and inhospitable ground is great for gumming up armys but sone wont care at all but really puts the problem of our slower guys hitting first. And use the destroyer, behemoth is tempting but destroyer is better imo as irusk really likes melee infantry.

I'd go with eIrusk, but then I think he's amazing, so am probably biased

He's a great help for those shock troopers you have, and can grant tough to the eliminators (put Battle Lust on them...) and Fire For Effect for your mortar. In fact basically every model you have listed are models I would consider with eIrusk, and I would say you could make a strong list without buying anything else.
