Yes there is and it's already an official option as described in the Essential Reader's Companion. The Expanded Universe as we know it exists as a parallel canon to the film universe. This is per Lucasfilm's Pablo Hidalgo and is the official stand on it. It can continue on EXACTLY as it is right now because it's not beholden to the films like the films aren't beholden to it. Again, Marvel. Other IPs have figured this out. Other IPs that Disney owns. Claiming that the new films are going to "wipe out" the EU is just fearmongering. The EU as it exists now isn't going away. Your mistake is assuming that the EU and the film universe are the same canon when they are, in reality, parallel canons as described above.
