Strantor, there's an easy solution for that, don't embed the EL wire in the lamp base, embed a slightly milky plastic tube that will allow you to feed the EL wire through it, easy to replace. Think about it, if you braid the three EL wire's together and feed them through the tube you'll get some very unique and pretty effects as the color will change slightly over the length of the wire even if it's set all on (one wire will block the other) Smooth color transitions would give a marque style flow effect up or down through the base.
LED base lighting has been done a thousand times and more before, you have some unique possibilities with EL wire, and using something like milk plastic tubing will act as the diffuser, so it's a win win, you can replace the EL wire any time it's required as long as the bends aren't too sharp. Nothing you can do with LEDs will look anything like EL Wire could.
