Could you make it so the armor plates for Jango's decal are the part that you can color for customizability?
I think for the jetpack you should do something like the HoverJet playertype but with limited fuel.
The helmet absolutely needs to come off.
or add the item to your inventory (which would be problematic if your inventory is full). So I'm thinking playertypes will just be for the custom chest/any movement changes (e.g. Jango's jetpack), and helmets will remain items only.
Clone troopers (and Mandalorians) have all sorts of utility pouches, etc. Just give them, like, 8 items and the inventory problem will be fixed.
Also, clone troopers don't carry much more than they're helmet, DC-15A/S, a Thermal Detonator, and
maybe one or two other devices.
Can you do Republic Commando stuff, including armor/helmet, DC-17m (with all three modes), and E-Web?
