I have used K&S brass tubing one inside the other for stuffing tubes in the past, but each sliding fit tube can introduce eccentricity and angular misalignment especially with short lengths. I wouldn't use that method on a stub and expect the wire to last long, if it is not perfectly aligned it will break at the nose of the stub.
I would just but a 2mm stub shaft, it will be much cheaper than several brass tubes if you don't have them already and will better alignment.
