A fun idea about the next special banner's fight style....

The silhouettes that are featured in the picture looks really really close to each other... I thought of an idea, though very unlikely, on how that could play into the possible characters. If they're that close, they must be a couple, right? So...
What do you guys think of the idea of possible pair units? Two people fighting together and considered one unit?
They look like they're holding a bow, perhaps? So if they were together, they could do some sort of strong double bow attack together.
Statwise, maybe they have more strength, but less speed since it's two people trying to walk together?
