Homepage Custom Theme and Redwood everywhere else?

Summary:

Is it possible to have or direct users via a link to one home page and then have the rest of the UI default to Redwood?

Content (required):

We are exploring options around the overall theme of Oracle. Given Journeys and Opportunity Marketplace default to the "visual language" of Redwood we would like to configure our homepage to be the same but the rest of the UI to navigate as if it were on the standard redwood theme. Predominantly, the solid green/white interface of redwood's home page was not received well which is why we made our own UI theme. This would permit a "best of both worlds" scenario if we could instead only change the home.
