Vampires (ghorst) vs Chaos Dwarves; how to?

So I know this is about to become an outdated question in about 4 days but I wanted to get a final vampires playthrough in before nagash, and decided to play Ghorst.

Drazhoath had a very strong start, wiping imrik and pigbarter ogres by turn 30; I myself have wiped out Greasus and Kugath and have tonnes of money. I'm in a fair bit of trouble now with Ghorst's usual zombo pile-on getting nuked by chaos dwarf artillery, trains, kdaai fireborn. I haven't yet got far enough in campaign to get my Vampires properly rolling.

My best idea so far is basically run an ambush army with whatever fast movers I can find (cairn wraiths, the giant green men, cavalry and wolves, a terrorgheist etc) - which is outrageously expensive - and stand ghorst inside the radius looking tasty with all his zombies.

I've even taken a weapon master banshee (sunder) and thrown it into the middle of ghorsts stack to debuff the chorfs. It's still super hard to pull off though and even with all that healing it's a brutal slog.

How are you supposed to counter Chaos Dwarves as Ghorst?
