Unless I'm conceptualizing this wrong, an impact hammer is not going to prevent flange damage. You're still going to have to place the hub in a vice or other fixture and then apply force to the freewheel. And even if you build it in to a wheel, you'll need the right remover. I certainly would not build one with a grinder.

You could try Muzi's approach but instead of using vice grips, use a strap wrench around the hub body. Considering the rim rotted off (how does that even happen?), the freewheel is probably welded to the hub, and a strap wrench won't do the trick.

With a good impact wrench you could hold the hub in one hand, the
impact in the other, and often spin the freewheel off with no other
tools required. Might want a good leather glove to hold the hub
