Bust out any remaining rollers and cage, and wipe out all the grease you can get out of there. Pressure wash the hub or clean it in the solvent bath. Once it is reasonably clean, heat the cone race with an oxy acetylene torch and quickly punch it through the three holes. Propane heat will likely work too, but you really want the heat in there quick, so it does not have time to get onto the hub. If the bearings failed, it may have been because of water contamination, in which case the bearing may be rusted to the hub. Or it may have spun a bit, in which case it also will be on tight. Or it may be cocked ever so slightly.....you would then have to figure out which way it is cocked and punch the opposite two holes.
You could also try some long threaded bolts and tighten them equally to force the cone out. While metric bolts are available threaded all the way, you may end up having to thread the standard bolts to get enough thread to get you anywhere. Oil the threads for extra force.
If the outer bearing is bad, then you may want to do the work to get into the inner bearing and properly repack it. And of course, the opposite side. And once you go for the inner bearings, you will usually find that the upper kingpin bearings are shot too, and they can be pricey and hard to find.
