Regarding Plato's cave allegory, I just put out an article today that might interest you, in which I naturalize Plato's pessimism about nature (link below).
I come at philosophy and religion with a little more pessimism, I think. I'm not a pure pessimist, cynic, or nihilist, but I turn to existentialism and to the cosmic horror genre to open up possibilities for a viable, late-modern pantheism or for some other worthy philosophical narrative that's compatible with science but that avoids falling into the various secular traps (scientism, neoliberalism, consumerism, etc).
I'd have a problem, then, with equating something as anthropocentric as love with the nature of ultimate reality. If "love" is a metaphor, it becomes an aesthetic matter which metaphor to apply to that which is essentially inhuman and unknowable. Darker or lighter metaphors would have different literary emphases and social impacts.
A collaborative story might be fun. Mind you, it might read more like it was written by yin and yang than by Bert and Ernie. Not sure how to email you, but you can email me through the "Contact the blog's author" section on my old blog (second link below).
