Update!
I spent about 2 hours driving on Sunday, which included a few high speed crashes. Aside from the riders arms snapping off at the elbows (yes the crashes were THAT hard and spectacular), the cowl STILL stayed on. The only damage was that my rider had some SERIOUS road rash, which I healed with a little Testors paint. Also one of the crash bars got a little tweaked (also a testament to how spectacular the crashes were).
