I asked a few guys in my unit and we came up with the following list:
- different base models for the pilot (male, female, different skin colours, thick, slender, musculous,...)
- different variants of clothing like cooling vests or underwear (since the cockpit is hot and who would wear clothes in the sauna?)
- tattoos
- dog tags and bracelets
- weapons (like the famous Sternsnacht gun)
- spots in various colours (since so many Mechwarriors drive with coffee mugs who spill easily)
- scars or artifical limbs
- cooling vests or clothing with colouring options
- rank insigniae related to the CW rank (great reward for events btw)
- generally a sort of "pilot lab" where we can customize these options ourself as opposed to an idea where basically a 4th cockpit customization slot is added where you can choose from different pilots
- changeable hair styles
- different helmets and helmet decorations, visible when you press the "tab" key
- "Hero"/special cooling vests like the one Grayson D. Carlyle wore (some sort of Star League outfit)
- differentiation pilot name / callsign - the latter being visible on the Mech or on the clothing/helmet
