IMHO the shamals could work if you sliver out the whole build.. I am also very unsure of the rules regarding mixing silver and black components - seems like there is cases where seatpost or stem or chainring just give the perfect balance (very personal opinion though). Also, I think it is important you put in on the streets first, and then decide on
matching the components aesthetically, fine tune the position etc...
