You *know* how hard SSTO is - and still you want to put these heavy things in one of them?
Items two and three in my list are required anyways; item 1 isn't terribly heavy, and item 4 doesn't need to be all that heavy since you are only worried about intrusions from one direction -- below.
>50 gees or higher peak acceleration is not unreasonable.
Please. What's the most you've ever taken whole body?
I hit a tree doing somewhere between 20 and 30 mph (not sure, I was asleep at the time -- hence the crash) in an early 80s Rabbit a number of years back. My injuries amounted to a charlie horse in my thigh and a hairline fracture to the bridge of my nose, both due to contact with the steering wheel. It was about 3a and I walked about a quarter of a mile for help. The front of the car had crushed maybe half a meter, probably less -- it was made before crumple zones were a standard item on cheap passenger cars. For the low end of the crash speed range, that works out to an average deceleration of about 100 gees, applied very quickly (fraction of a second).
