I've had a go at expanding the 'Oops, all constructs' Petrifex idea out to 2000 points, let me know what you think!

2000 on the dot.
I’d love to vary the heroes up a bit, but honestly the Boneshapers are just so much better, especially for a list like this. The heal/res component is an ability rather than a spell, so they can all spam it on their Immortis bodyguards, which will hopefully allow for the scoring of the Sculptor’s entourage battle tactic, as well as the Cremation and Termination grand strategy. The Stalkers are there as disposable hammers (potentially scoring the much more difficult Edge of Obiliteration tactic), whereas the Morghast live in reserve to project power by threatening a backfield objective or sniping heroes/ranged units (they can reroll their own charge as elites, and potentially fight first if they roll well). The Carrion lets the list bully hordes off objectives, as it can’t be dispelled in that turn if cast by the general. The list makes good use of Nadirite Weapons (pretty much everything can be at least D2 -2 rend), and the Petrifex -1 damage effects everything bar the bodyguarded Boneshapers. Finally, there are eight units on the table for maximum Relentless Discipline goodness.
