One way I'm doing something kind of similar for Battlesystem Units in my AD&D 2E game is to use the Tooltip section of the Token for reference to Stat Blocks that don't change, (so you just hover over it and it shows the basic range/movement/attack & defence values etc) and adding my own Attributes using the standard Character Sheets to draw through Macros for things like Attack Dice, Armour values and Hit Points, so that the Macros have something to look at for sources. That's how I would handle the situation for Ship To Ship combat. In adition to the Handout, you can probably use a Template to draw and call up a chat based macro update of current stats beyond the three you can see on the token from the attributes. (I don't think its possible to update the entries in a Handout like you can on a character sheet, though if that IS possible I would love to know how because that would be a BIG help to me right now!) You wouldn't be able to open the template like a character sheet, but it would be available at the push of a button and you could amend the notes on a standard character sheet, handout or the token. Either way, using the standard character sheet (if only for the ability to add as many Abilities/Macros as you want) is probably going to be the way to go. You don't need to use anything else on the CSheet beyond your new bespoke Abilities and Macros. It's been many years since I played the d6 Star Wars game, and don't remember anything about ships, so not sure about how locations, shields, armour and hits work
