I guess you're saying that the normal "heavy" bumper does more damage if you get hit from the side?
If so then would specifying straight frontal or rear impacts make more sense?
Either way... messing around with what is your first line of defense in most accidents/crashes is probably not worth saving 50-60lbs from a daily driver. If it's a track car, go for it.
