My iPhone got stolen - can I back up that phone's data on another iPhone from iTunes backup?

Question

Details: My iPhone 4 was stolen and I activated Lost Mode on iCloud. A lot of time has passed and I've given up the chance of getting it back. My question is this. I'm trying to back up a new iPhone with my old phones data that I saved on iTunes backups. When I try to back up my new phone with the stolen phone's data, it says I must first disable Lost Mode before I can do this. Since the phone was stolen, I can't use the phone to disable Lost Mode and I'm if I go to iCloud and remove the device permanantly from "my devices" I'm afraid it will delete my iTunes backup for that phone and all the data I'm trying to transfer to the new phone. Does that make sense? How can I turn off "Lost Mode" without deleting my iTunes backup for my phone that was stolen so that I can back up my new iPhone with my old phone's back up file on iTunes?
