iPod - worth to play with it ???

Hoi Guys,

I am looking everywher for iPod line out connection, whether docking satation or preferebly cable to 2*RCA.

What I found was:

It goes from 30pin to mini RCA socket - adapter mini RCA to 2 * RCA female socket - stereo RCA. It seams quite long and complicated;

 It is exactly what I am looking for, but UPS from USA would cost 68$ and perhaps customs taxes.

Do you think, that it would be possible to adapt it. I mean make the cable longer and fix 2 *RCA plugs.
Will it be possible to connect new cable and split probably one "nul"?
