would you like to try the sheldon method?

use a hub with hollow axles, one that works with a QR, and chop the axle so that it sits flush with the lock nuts.
now, instead of the axle sitting in the dropout, you have the skewer sitting in the dropout, giving you more room to work with.

and if that doesn't give you enough room, which it should, then you can file some slots into the dropout if the dropout has enough material.

be sure to use a shimano or campagnolo skewer.
