Check with WI again. About 10 years ago the WI DMV stance was find the original title, no other options. However, more recently I checked into the process when dealing on a vehicle and they had a form for titling without the original. The deal fell through, so I didn't actually go through the process.
I did go through the process 10 years previous and did have to title a truck in MN first. MN DMV had me submit a statement from previous owner selling me the truck and then take out a bond based on current value. Bond was for 10% and I got that through my insurance company. Once the bond period was over, title was clear in my name.
Keep us posted. Won't be the last time someone encounters this.
