Seconded. All the options given have uniquely sculpted details that would make Gladiator next to impossible to accurately pull off.
what are you talking bout? there is nothing too different to the Gladiator.
say for example, if the were to use the Doc Samson sculpt, all they have to do is give him a cap, new head, hand and feet, some of those shin guards and a new diamond symbol. that it. there is no need for a new sculpt.
Doc Samson's upper torso has that square opening around the neck, Gladiator costume doesn't, so that piece isn't accurate. Samson's belt is part of the lower torso's sculpt and it isn't even close to Gladiator's either. Samson has the sculpted sleeves in the upper arms that wouldn't work for Gladiator either. And finally, Gladiator doesn't have bootcuffs. So the only two parts that are readily usable are the lower arms and upper legs.
They could use Samson, he just wouldn't be very accurate at all. They just need to produce a good large sized "blank" body in the vein of the Bullseye/Quicksilver sculpt that could be reused for several characters.
