This is an OLN issue? i.e. You need hollow axles and QR skewers cut down to fit a narrow hub/frame? You may be lucky with a normal front working as a narrow rear. Many hollow axles have no thread in the centre so make sure there's enough thread on the axle that your cones don't 'bottom out' before being snug with the cups/bearings. Might be best to assemble the whole thing, including freewheel, with the uncut axle, try it in the frame, measure from each end of the axle to where it needs to be cut, then disassemble and cut the axle.
The answer to your last question is yes... but you may have to use a die to extend the thread for the nut further up the QR skewer, and then cut off the excess.

That was a stupid idea...different diameters.. in fact subsequent posts are making this whole post look redundant..
