Since your fabricated C6 uprights are 1.1 pounds heavier than stock but your hubs are 1.7 pounds lighter than stock it seems logical for one to replace the stock hubs and uprights with yours. Not only would there be a savings of .6 pounds but one could increase the bad ass factor by 10.
Better design + lighter weight + more strength + serviceable = Cool!
In the fine art of negotiating, that is called a Win/Win!!
