A unit of Kislevite Winged Lancers or Irondrakes good?

Not as they are in canon since those are actual military units and not mercenaries. You could do something like the Winged Lancers where shamed or something and became mercs or they're a bunch of disowned sons of Boyars or something like that. Irondrakes are a lot harder to justify being a high tier dwarf unit.
