The two ideas that sound like a shot are maybe BMX pegs that are modified into small platforms, or possibly an heavy duty rack with a seat. Anybody got experience with heavy duty bike racks?

Personally, I'd look for a heavy duty touring or utility rack and have it welded to the bike frame. Like this:
