I am sure you now know that aluminum and steel will weld together with time. Be sure to coat aluminum quills with grease before using them inside a steel tube. Somebody on the forums some years ago posted that brass grease (?) is the appropriate grease for this purpose.
Yes, I have tried that impact through the fork hole, although it seems like pushing on the internal wedge wouldn't really have the desired effect.
I have a feeling my LOOK carbon fork will die of UV exposure, or the cartrige bearings in my headset will need replacement before I'm able to get the stem out. Some day I will just have to saw through my forkstem, donate it to my LBS to display as a warning to others, and have a good cry

At least I've already gotten a good six years of year-round daily commuting out of the fork...
