For some reason, my first ideas were all except for one pop and ice cream related, so I didn't post. But I'll take Lowell's example as permission:

Boston Cooler
Creme Soda
Towne Club Lemon-lime
Sander's Milk Chocolate Fudge [[or Caramel)

These two are more a Michigan thing:

Blue Moon
Superman

Honky, the exception was also one of yours:

Koch Coke
