I don't have a csvt I just have a normal SE so I don't have leather or even cloth panels. You on the other hand may want to look into some leather dyes to change the color of your panels if you decide to go that route. I know a member named dion used a kit from leatherrenew.com to dye his seats and he said he had nice results.
Personally, I think that black doesn't go that well with midnight blue as far as two tone interiors go. I would prefer something with a bit more contrast.
