Afternoon project? 1973+ bumper reinforcment removal for weight reduction...worth it?

When my 75 Duster got rear ended by a Ford van back in the mid eighties that big collision bumper saved my car from catastrophic damage. I was hit hard enough at a stop light to be launched forward several feet, and expecting the worst I got out to have a look. The only visible damage at the time was confined to the bumper guards and visually it was very slight. Meanwhile the vans headlights were left pointing in two different directions, the bumper was shoved into his radiator which was loosing its coolant all over the ground, and his grill was destroyed. I was able to drive away and ignore the minor damage. He was towed away. I get that the car looks a bit better without them sticking out there like that, and the weight savings is a real temptation, but I think I'll be keeping my collision bumpers.
