Bevel Tool constant radius

I'm missing a feature in the bevel tool for constant radius instead of offset or width. I'm doing a lot of hard surface modelling and beveling is always a pain as soon as the angle isn't 90/45° deg.

What I would like to see is an additional mode in the bevel tool with a constant radius. The radius of the bevel should always be the same, no matter how big the edge angle is. Since the amount of segments per degree would be different based of the initial edge angel before beveling an additional mode with a constant segments per 360° should be add as well.

In the image below you can see, from left to right, base model, result from the current bevel tool, and the wanted result with a constant radius bevel.
