I'll think up some justification for them being there, similar to what you suggested probably. They'll be similar to the Polish Winged Hussars IRL with heavy plate, a lance, shield, sword except instead of two normal pistols one repeater pistol.

As long as they're wealthy children I could see that happening, being sort of like Kislevite [url=http://warhammerfantasy.wikia.com/wiki/Voland%27s_Venators]Voland Venators[/url]. Not sure how I feel about them actually having the wings or the pistol. For the wings it could be that its their insigna but as for the pistol, I'd probably allow like one normal pistol. Handguns aren't cheap to begin with and repeater pistols would be even more so.

If that doesn't work, I can say that the Irondrakes are just rich sons of Dwarf Lords and such who's inheritance is going to brothers and such so they decided to band together and reclaim this for themselves; the squad would be called "the disowned" or something.

My main issue here isn't that what you're proposing is too powerful or whatever, is more that its straying really far from canon. Dwarves by nature take honor and oaths very seriously so even if they were ticked off their brothers were getting the good stuff, they would still stay loyal to the wishes of their family and holds. Ironbreakers/Irondrakes are also old, extremely elite warriors in expensive runic armor who also take their oaths extremely seriously and wouldn't think to go against their king's wishes. Dwarves don't think like humans in this case, they wouldn't just go do their own thing because they couldn't get some inheritance, especially if they are effectively elite honor guards in the military.

Even if they were shamed in battle or something, it is more likely they'd end up as Slayers and give up their equipment.
