I actually have the models to field this

or at least, I will, when I get the last 2 units of Runeshapers in a few days.
Doomshaper (+7)
Earthborn - 10
Slag Troll - 6
Krielstone Bearer + 5 scribes + elder - 5
Runeshapers - 3
Runeshapers - 3
Runeshapers - 3
Runeshapers - 3
Runeshapers - 3
Runeshapers - 3
Janissa - 3
Total - 35
Only tier 3, due to having a single dire troll instead of two. I could drop a unit of Runeshapers to upgrade the Slag to a Mauler, and be tier 4... but then I'd only get to place 2 walls instead of 3 (due to tier bonuses).
I think this list will definitely be able to deal with high
DEF, but high
ARM could be a problem. Trading in a unit of Runeshapers for the Mauler upgrade would probably help with that. Or trading 2 in for Mulg, but I'm trying to get away from using Mulg! And I'd like to have as many of those units as possible, giving me a full krielstone at the start of the game. With the Stone and the Earthborn animus + prevalent walls, the beasts should be at a solid +4
ARM
The slag troll is nice, because Doomshaper has so many anti-warbeasts spells, that the slag's ability to get an extra dice on his 2 ranged attacks against jacks makes the list a bit more "all comers".
Thoughts and tips appreciated
