You are right, the blue-citron match was originally for a turquoise Yeti with yellow components, but one you have a paul hub laced to citron rims you can't throw everything away, can you?
Nitto stem? I can find a really nice Spesh forged stem with high rise, but I like that inch of travel, you know... Actually, after installing the moustache handlebar, I could change my mind.... a nitto-nitto match would be very stylish
BTW, Maguras really make a world of difference. One finger braking makes things so much easier...
