A modern AND vintage nursery?

My sister-in-law is expecting her second girl in a few months and we've been brainstorming nursery decor ideas.  She loves Hello Kitty, but doesn't want it to be cheesy and over the top.  Sh, she found this nursery bedding set online at Target at a great price.  It's cute and vintage Hello Kitty design with the use of fresh modern colors to balance. 
Our new idea is this: Play up the deep fuschia "raspberry" color and use a lot of the pale celadon green to balance it. Aside from the bedding itself, and perhaps a few small details like knobs for the dresser, there would not be any Hello Kitty stuff. Some heart decor bought off valentine's clearance may come in handy?

Tossing around the idea of doing a white chair rail with the raspberry color below and the pale green above. Another fun way, one that is perhaps more subtle, is to buy a used chandelier and spray paint it the raspberry color similar to the one pictured below.
