Why would you want to do that, the um3x is a great universal iem, it shares the same drivers as the es3x which is regarded as the no. 2 iem around after the jh|13 (correct me if I'm wrong). I personally wanted the um3x instead of the tf10 but no one wanted to trade my hd650 for one at the time. SO you'd get a pretty awesome custom for $120(new price methinks) instead of having to pay more to add drivers to fill in where the original was flawed.<enter TF10 fanboy rant's here>
But on the contrary it would be awesome to put together two sets of um3x's and then make a um6x custom.
Btw GW on reading all the pages - I did that too before I bought mine xD, - It helped me decide against artwork lol.
