I've played 5 or 6 ironman "characters" in ED now. I'm NOT wiping my save, so my rules are identical to your Ten Commandments except:
1) No repairs except for Wear And Tear.
Wear And Tear isn't performance based, so in my head it doesn't represent the same thing as say fixing the Shield Generator etc.
7) No Shield Boosters, Shield Cells, AFMU or Hull Reinforcement allowed.
It's really possible to overpower the defensive capabilities of ANY ED ship if you ignore cargo racks/fuel scoops/exploration kit. Taking out the defensive Add-Ons makes the game tougher, but also means you won't be tackling Anacondas in Eagles without any real risk of damage.
8) No discovery scanners allowed
Put simply, I took my second Sidewinder out with a Basic Scanner, and tried to find a Black Market to sell 2T of scooped metals (Gold I think). By the time I'd travelled through 40 systems (a 1E Scoop takes a couple of minutes to fill the tank but only costs 303Cr. That trip took an hour in itself) I had made about 38,000Cr in Exploration Data, mostly from just the basic stars and the odd nearby planet. That doesn't fit the basic premise of IronMan to me. I'd be off out of unpopulated space for a day, make 2MCr in exploration data, and back to fight my way up to the Vulture in an A-Class Eagle. No D-Scanner makes Fuel Scooping MUCH harder too. I just destroyed that Sidewinder and on the next one I binned the D-Scanner.
10) Upon ship destruction, the 0Cr "Trevithick/LHS3447" must be chosen (I think different people get different options depending on where they started at the beginning of the game?)
In order to cope with not deleting my save game, when I started off I bought my first Sidey and crashed it to clear my bounties/exploration data that I hadn't cashed in. The second one was "#1"
I made a note of my exact Cr amount at the start of each "character" and subtracted 1000Cr from it and wrote that number down. If anything I did, e.g. outfitting, caused my balance to go below that figure, I reverted to the previous loadout. That way I never spent over 1000Cr from my starting balance.
Experiences so far? I haven't made enough Cr to buy a KWS yet, so have had my ship badly damaged for 230Cr bounties.

In general, smaller ships like Sidewinders and Eagles seem to have larger bounties anyway for some reason. An Elite Viper (TOUGH fight in a Sidewinder with twin Burst) and a Competent Cobra (not quite as tough as it didn't have turrets, but I only had one Burst on that Sidewinder so I had cash for other stuff) both had me down to about 70% Hull and both had 230Cr bounties. Yeeep.
My 2nd or 3rd fight in my most recent Sidewinder had me against an Expert Eagle had the 5000+Cr bounty I needed to get a couple of Lasers, bigger Power Dist and Shield Gen. That Sidewinder ended with me being interdicted whilst fuel scooping by a Deadly Eagle. I'm on my work PC, and Outlook had popped up a notification in the background, so my keyboard wasn't locked to the Elite Client when the fight started. Switching to desktop and back took a few valuable seconds, and I'd put my Shields offline whilst I was scooping to keep the heat down. I finally got into battle, but was at 43% Hull by that time. I should have tried to run straight away as my shields never came online. Module damage meant I couldn't get into SC or Hyperspace (or indeed do very much apart from crackle and spin). EJECT EJECT.
Sorry, long post. Ironman is definitely a valid playstyle for ED, and it
definitely shows that a second CMDR slot would be a fabulous addition for the game. Also, it's exhilarating and interesting, gets you thinking, and going back to a Sidewinder and 1000Cr when you muck up is pretty humbling when your garage has a 13MCr Vulture in it. I've never flown the Sidewinder as I got the free Eagle in Gamma, and it is a surprisingly tough little ship with even basic upgrades.
