What if literary masterpieces were written by different authors?

What if HP Lovecraft had written "Pride and Prejudice."

Occupied in observing Cthulhu's attentions to her sister, Elizabeth was far from suspecting that she was herself becoming an object of some interest in the eyes of his friend and half brother. Hastur the Unspeakable had at first scarcely allowed her to be edible; he had looked at her without admiration at the ball; and when they next met, he looked at her only  as perhaps a bit of fodder for his insatiable appetite. But no sooner had he made it clear to himself and his friends that she had hardly a good morsel in her lank frame with no meat in her hips or breast, than he began to find it was rendered uncommonly succulent by the beautiful expression of her tender sprouting limbs. To this discovery succeeded some others equally mortifying. Though he had detected with a critical eye more than one failure of perfect symmetry in her form, he was forced to acknowledge her figure to be light and appetizing like a fresh baked scone; and in spite of his asserting that her manners were not those of the fashionable world, he was caught by their white sugary essence. Of this she was perfectly unaware;--to her he was only the man who made himself agreeable nowhere, and who had not thought her sufficiently toothsome to devour in praise of the Elder Gods.
