I haven't seen one, but it's probably feasible. You'll have to fab a frame
to hold the hammer, and it'll need to be fairly massive to absorb the
recoil. Remember that the mechanism will be exposed to intense radiant heat
from the workpiece, and think about shielding for the electrical bits and
any component made of plastic. The only street pounder I've used ran on
air, so I have no idea whether the unit shown in the foto is 'throttleable'
or not. If it is, then you'll have to come up with some sort of linkage to
the trigger that you can operate with your foot, because you'll need both
hands to control the work unless you have forearms like Popeye.
Powerhammers can snatch the work right out of the tongs if you're not
careful. You'll need a clear area around the hammer, because it Will Throw
flux EVERYWHERE. 2500 degrees is H-O-T, and it will start fires in
combustible materials like shop rags, wooden workbenches, the motorcycle in
the corner... Let us know how it comes out.
