Benoit,
You are right in assuming that a bumper that is stiffer than the
chassis rails may cause more damage than good.
This is what I have in mid for a new front bumper project - a strong,
heavy duty cradle for the winch, which will strengthen the front
chassis rails, and light sections on each side to give some protection
to the lights and front quarters. That way an impact to a side will
not pivot the chassis frame, although it will not entirely prevent
damage to the bodywork. But that's a lesser problem than a bent
chassis.
I am not, however, sure about mixing aluminium and steel for the
bumper mount. A heavy steel structure at the front will vibrate on
rough roads. Because aluminium is stiffer, compared to steel it is
also easier to break under stress. I think making some calculations
and analysing stress points would be a good idea for your experiment.
