Not sure why you'd want to use the original axle, but Sheldon said it could be done. Frankly, though, I want to have the extra 2.5-3mm so that the seating is ample.
What do your dropouts look like?
The trick with QR axles is that that the axle can't protrude beyond the dropout AT ALL. If it does, the QR will bottom against the axle rather than clamp tight against the dropout.
