For me such ironman mode would be that you only do not have insurance coverage, not that every time you die you start with a Sidey and lose everything, as you would have an universe full of Sideys and Eagles, basically you would keep your credits (maybe even stored ships) for the next life making the loss sting a lot, but not be totally crippling. (most variations on this theme would also be fine with me; ie have insurance but no default 200k/600k coverage at minimum, have insurance which is a lot more expensive and so on).
Oh, ok. I didn't think of that. I always thought of it as requiring a re-roll. I move to refer to your version as "Draxxen" mode.
