Well, yes.  That's exactly what I described the first time, a large 
wire that carries most of the current, with a much lower current 
bypassing the shunt and going through whatever sort of gauge is 
desired.  Another term would be voltaqge divider, an array of 
resistors to pre-determine how much current goes through which path 
and thus what voltage each will see.  The difference as you describe 
it is that the shunt would be to reduce a current or voltage by some 
moderate fraction, in your case 1/2, which is to say to split current 
across two different paths by 50/50.  With a conventional current-
detect circuit it might be to divide currents by 99% and 1%.
