Although that would save weight, it would not affect aero, so it really is off topic. But if you want to start a thread about it, I'll weigh in on how much weight you'd save and why some of those components pull their own weight.

Purpose—The purpose of this document is to provide minimum static design guidelines for curbstone clearance, approach, departure, and ramp breakover angles. This is to minimize damage, if any, in normal vehicle use conditions. This document also encompasses all current worldwide regulations and requirements.

Shouldn't a standards document be in the public domain?
Phil, do you know the rest of the relevant angles and clearances recommended by the SAE? And how low do you think the Insight's Cd could go within those limits, and without any drastic reconfiguration of the windscreen, etc?
