Seeking your input...Should I cut the lantern posts or turn them into an arbor..?

Got the lanterns painted and hung. Now I'm wondering if I should trim the boards... or add more boards across the top to create an arbor. Part of me likes the current simplicity of the boxes, but part of me can totally imagine a homespun arbor, dripping in flowerey vines and sparkly white lights...whatya think?
