I think dwarves don't need any fantastical rules to make them feel right on the battlefield. Here's my list for a 24 point DR warband.
Axemen and Hammerers : Heavy Foot x 4 (4 points each, one with the Leader trait)
As you can see above, one unit includes the dwarf king and counts as the Leader unit for the warband.
Crossbows : Heavy Missiles (4 points)
Bear-riders : Heavy Riders (4 points)
I've got another unit of bear-riders painted up that can be swapped in as either a hero or alternate leader. For a heroic unit, I'd classify them as Elite Riders with the Level-headed trait (8 points) and drop one Heavy Foot unit. Or just add them in for a 32 point game. 🙂
So it's a six unit warband and the use of all heavy units makes it a slow, but hard-hitting force. Just as dwarves ought to be.
As you may have noticed, they are based on group bases. These are sized for Hordes of the Things. I can easily put together a couple of 24 point HotT armies from what I've got here:
Dwarf Army I
Blade General (dwarf king) @ 2 AP x 1
Blades (dwarfs with axes and hammers) @ 2 AP x 9
Shooters (dwarfs with crossbows) @ 2 AP x 2
Dwarf Army II
Hero General (dwarf champion on bear) @ 4 AP x 1
Knights (dwarf bear-riders) @ 2 AP x 4
Blades (dwarfs with axes and hammers) @ 2 AP x 4
Shooters (dwarfs with crossbows) @ 2 AP x 2
