I know this event already took place... just curious from a TO perspective. For WYSIWYG, would you consider a Mournfang Hornblower, Skalg, Banner bearer, ECT, that have a Culling Club modeled on them but the regular models in the unit have Gargant hackers to be legal? The FAQ on GW about such units states that you don't have to model the special models (such as Skalg, Banner Bearer, ect.) as they are expected to have the weapons as the rest of the unit. I modeled mine like this due to it being more ascetically pleasing to me to have the variance and it appears to be in line with GW's rules. I also alert my opponents to this fact prior to a game. I just wanted to see what you guys thought.
Here is the FAQ I refer to:
Q: How do models like horn blowers and standard bearers work? Do they lose the weapons they would otherwise carry, or do you just gain the benefits of the upgrades without penalty? A: You just gain the benefits unless specifically stated otherwise. The model is assumed to still have any weapons it had before it was upgraded, even if the weapons are not shown on the model itself.
