It is wise to...try many themes, that so you may find the right and inspiring one... Improve the suggestion of each object however humble, however slight and transient the provocation. What else is there to be improved? Who knows what opportunities he may neglect? It is not in vain that the mind turns aside this way or that; follow its leading; apply it whither it inclines to go. Probe the universe in a myriad of points. Be avaricious of these impulses. You must try a thousand themes before you find the right one, as nature makes a thousand acorns to get one oak. -September 4, 1851
The layout certainly fits the description of a new theme with slight and transient provocation, but I think it's pretty clear that this isn't the acorn that begets the oak.
