Here are some opinions on those ideas
1. yabsuhlutely not why would you kill the cuff do nawt do that
2. I'd have to see a silhouette of the new skirt type to really understand what you're talking about, but the picture in my head looks kind of dumb. That said, it's really time for one skirt. Having two skirts has always gotten me. Also, pencil skirts in the military have always struck me as dumb.
3. Yes, yes, yes, yes, yes. Maybe even make a fully white uniform.
