But sunlight is not coherent. And in order for light to interact directly with itself, that would require electromagnetic fields to be nonlinear. There is no evidence that either occurs.

Because of cohesion forces between molecules, water molecules are not homogeneously distributed in the atmosphere, but can often be found in groups (droplets). Reasoning from analogy could suggest the hypothesis of small cohesive forces between photons.
Except that Maxwell's equations for electromagnetism are explicitly linear. They would need to be wrong in order for photons to interact directly. There's no evidence they are. I don't think you really understand what you're proposing.

Take the case of fullerenes. Nobody would have been able to predict their existence from our physical theories.
Not so. They are easy to predict: they have the same local bonding structure as graphite. The difficulty was manufacturing and detecting them.

There will be fighting at the door of the Legislative Palace, and the struggle within will be no less furious." - Bastiat, The Law
