We are using Kalatheme with Panopoly and radix layouts. The home page (and some subpages) design calls for a persistent top nav bar, a banner region, main navigation region and the content region. See attached layout for visual explanation.

We want the top nav and main nav regions to remain in code while the banner and content regions are controlled by the page manager. Is there a way to accomplish this using Kalatheme's one-region approach? If so, how can we move the banner region above the main nav region while still allowing site builders to manage the banner content using page manager?
