Nexus 900 - Headphone routing - Line level

Anyone know of a way to re-route the headphone out to a back output... or better yet.  headphone output as a line level out so it can be routed to a sub mixer properly?  

Im using wireless in ears so cosmetically  it makes no sense to have a big cable sticking out the top front.  

Technically speaking it works as is but having the proper signal and impedance for the sub-mixer input would be better....
