What about fussy cutting some pink/red roses and using them as the accent?
I've seen a 1600 inch quilt with a black and white geometric used as the accent, and one with purple, and one with white... let me see if I can attach the pics - if I saved them...
Strictly my humble opinion, but I think several of those fabrics you plan on using are just plain boring, if not a little homely. Again, IMHO
