Troop Spam list idea, but which caster and BG?

So, I have this dumb idea flying around in my head:

Yeah, i think you can see where the list goes: Drowning the opponent in Weaponmasters, but I am a bit stuck on what to take as caster and Battlegroup.

Considerations:
- Kaelyssa with Discordia and Moros. Moros offers a hit-buff against living Models, Refuge on Discordia is always great and with Blur+ Kinetic Field  + Feat there is some protection against shooting.
- Thyron: Onslaught offers Pathfinder and the Feat is a hit-Buff. Army-wide Blessed gets around spells like Roots of the Earth.
- Goreshade4: Hexblast for Upkeep Removal and Freezer as a Hit-Buff.

Any opinions or maybe even another option I have not considered? My other list would be Issyria, so she is out of the Question.
