Mando,
If I had your setup I wouldn't chance anything, however....... as we all know these are never finished. So I would re-anodise all fittings the same in either black or a dark grey (matching your footboxes) but keep your braided hose.
I have spoken to an anodising place who have done AN fittings and they advised that as long as all of the swivel connections have a connection on both parts then the colour will take and is a simple job.
I have used these guys in the past and will again in the future, I know they are not local to you but may be worth a call for any q's.
A Grade Anodising
