Role-assignment suggestions:
Battleaxe strikes me as a Sniper - especially with the OVL - though almost all of the Warhammers on the MUL are Brawler types (but that may just be a default)
I would consider both the Cestus and Vulcan as Brawlers. However, based on damage on the Cestus, I could also easily see it acting as a Juggernaut.
Gladiator should be a Skirmisher.
Hornet and Falcon look like most Strikers and Scouts (not enough armor for Skirmishing). Could go either way with these two.
(My opinion mostly parallels the Role descriptions listed in the ASC p.134-136, though opinions and results vary)
Model Coding Suggestions:
I wish I knew more about BattleDroids to help clarify/verify the original intended designs (the Cestus *looks* like a Cestus to me, despite missing the GR barrel). The only thing I can suggest is to find the predecessor or like-typed unit, assign the prefix code, then adjust the suffix to identify it as an earlier model. When done, assign "-BD" as a second suffix, for obvious reasons.
Battleaxe: if you would consider it kin to the AgeOfWar/primitive model, perhaps make the prefix "
BKX-" ...otherwise, the -1K works for me.
Crossbow:
CRB-4A or -5A (preceeds -6B)
Cestus: based on the Crusader,
CDR-2R (preceeds -3R)
Vulcan**: the "VLC-6N" is actually an aerospace fighter ...so that's no bueno. Either
VL-3H or
-4H to represent the "heavier" version (I see no known designations assigned between -2T and 5T on Sarna, so this would be where I would place them)
Gladiator: fine as you have it
Hornet: looks like a Wasp predecessor to me.
WSP-1T or
-1X or
-1A-BDFalcon: looks like a reposed Hornet, or vice versa ??? tough call here, not sure which was first. Alternatively, this one could be a Phoenix Hawk (the pose with the gun down looks like the model I own; its just missing the iconic backpack jumpjets)** ...in which case, I'd propose
PHX-1X-BD** While I don't take everything I read off Sarna too seriously, the "BattleDroids" search had some interesting details.
The images attached led me to conclude the differences between the Hornet and Falcon (cutouts were nearly identical), and the mention of the "
Merlin" made me go examine it's stats. While not exact, it's size and movement profile is similar to what you have for the Vulcan, though armor and damage are both slightly off.
Although not up for discussion on the matter, if you would consider the BD Vulcan as a Merlin, I would recommend
MLN-1X-BD for a model name.
