yet another solution...
I once bought sockets for RJ45 and connected them in a crossed manner..
I used that when I had a need to extend a cable using two cables and in the
same time to cross them over..

1st cable crossing sec. 2nd cable
this way you can re-cross the cables to be straight again..
I think you can also find RJ45 extentions much the same as those used to
extend phone lines and re-cross them to the same end..
the prob is that you need a cable ( even a short one ) for each extended
line...
the wires need to be crossed are if I remember right..
1<--->3
2<--->6
all the rest are kept straight
