I need help making Sandy Chapman valance into a panel

My client likes the Sandy Chapman valance, but needs coverage for sun over her window and she asked me if I could make the top of a drapery panel like the valance, but yet let it be long. (She doesn't want the valance over panels because I've already asked that option).

I could think right off hand to maybe make a cuffed panel with large spaces in between finials to get the swoop effect and then maybe add the horns on separately?

What do you think?

Thanks, Fonda
