If the steerer is long enough, you could sleeve the tube internally: cut off the bad bit, make a 2" sleeve that sticks up an inch above the cut & stops an inch or more above the crown, heat-sink the crown (wet rags, submerge it in water, e.g.) & braze on the top of another steering tube. As long as tube is straight, the join doesn't prevent the lower headset cup from sliding on and the sleeve doesn't interfere with the insertion of the stem, this should work. If the result doesn't please you, you've only lost a little time & material. You can still do what your omnipotent leader commands.
I am suggesting this because chrome plating can look quite different from different sources, and it may be worth the effort to keep the original finish intact, assuming you have chromed head lugs & the fork's chrome matches them now.
