A 230 MPH impact on the human body will tear it apart, even with another human body. Remember the skydiver who crashed into another at an airshow and lost his leg? You wouldn't have bodies, you'd have an abatoir. I saw an online pic of a motorcycle victim, not a pretty picture. When I was a kid, one or more of the tabloids specialized in pictures of gruesome crashes, very bad taste.
Secondly, translating damaged metal in plastic is extremely difficult to do. The two materials react differently to stressors, and I've very rarely seen it done effectively.
Finally, if you plan on showing this in any contests, you may be rebuffed, as well, Certainly, any club adhering strictly to IPMS Rule 5 would minimally have it behind a curtain or refuse it entry at all.
In short, not a good idea, IMHO.
