Well a QR skewer is considerably less durable then a thru axle; not to mention, the diameter is pretty small, so just getting a nut to put on there wouldn't work.

A track nut is designed to take a 10mm axle, and a qr skewer is a lot smaller than 10mm. If you're going to get a proper set of SS wheels eventually, I'd just flip the skewer around and see if the other side holds better. Crank it down really tight and hope it works until you upgrade.
