SS volunteer units typically used established symbols from [insert nation]'s heraldry, so it would make sense for a US division to use something quintessentially American. Possibly the bald eagle from the Great Seal, or the Statue of Liberty. Maybe even the iconic snek from the "No Step" flag.
I've seen some alternate history autism about a W-SS George Wasington division complete with his profile on the collar tab, pic related. Not a very good design IMO, because it's not immediately recognizable.
tfw General Patton wanted to utilize "honorable German soliders" including the SS to attack the real enemy of Europe (Bolshevism) but (((they))) fucking assassinated him.
