IMHO it would be better to do away with insurance altogether. You buy the ship and always have it, if you die you re-spawn with the same ship and modules.
Think about it - more people would play in 'Open'. More people would go in for PVP combat. Their would be epic battles. People who want to fly an Anaconda or Type 9 or whatever would still have to put in the effort to get it.
IMHO, no, then we fly absolutely risk free? Remove any sense of anything, just hit that reset and boom! Everything is shiny and new? On the contrary I think if you lose a ship for a while you ought to have an increased insurance cost, say increase it by 1% for each death up to a max of 20%, with 1% decaying every x-amount(say, hour, or two hours, but not ridiculously long) of game time back down to the standard 5%.
Alternatively they could garnish your income for a period of time while still providing 5% insurance, then of course if you die again the garnishment goes up.
The consequences add a huge amount of immersion and danger to the game. Consequence free is boring, it takes the bit of depth we have and throws it in the gutter. The little bit of Open I have played the risk factor comes entirely from losing your ship AND the cost of it. Take that away and you take away the thrill, sure everyone could play open, and you'd take half the fun of it away.
