I've seen, and have been able to make, some Dolphin sites that look nothing like stock Dolphin. It takes more work, but it's doable.

There are a lot of large and nicely-done Dolphin sites, but none of the owners of these sites hang around Unity, and I don't blame them. Mostly because these people hire developers to create the site, and they choose Dolphin, so there's really no connection to BoonEx, except for the license in the developer's account.
