HP fandom - young heroes in love

This is an opportune moment to again mention my fixation with the possibility of a Harry Potter/Dune crossover. The scene just outside the hospital ward where Harry recuperates after the final battle in R.J. Anderson's “Endings and Beginnings” had immediately sprang the following paragraphs of Dune to my mind (though it has taken me quite a while to find the passage in the text):

Paul remembered he had rushed out to find Chani standing beneath the yellow globes of the corridor, clad in a brilliant blue wraparound robe with hood thrown back, a flush of exertion on her elfin features. She had been sheathing her crysknife. A huddled group had been hurrying away down the corridor with a burden.

And Paul remembered telling himself: You always know when they’re carrying a body.

Chani’s water rings, worn openly in sietch on a cord around her neck, tinkled as she turned toward him.

‘Chani, what is this?’ he asked.

‘I dispatched one who came to challenge you in single combat, Usul.’

‘You killed him?’

‘Yes. But perhaps I should've left him for Harah.’

(And Paul recalled how the faces of the people around them had showed appreciation for these words. Even Harah had laughed.)

‘But he came to challenge me!’

‘You trained me yourself in the weirding way, Usul.’

‘Certainly! But you shouldn't –’

‘I was born in the desert, Usul. I know how to use a crysknife.’

He suppressed his anger, tried to talk reasonably. ‘This may all be true, Chani, but –’

‘I am no longer a child hunting scorpions in the sietch by the light of a handglobe, Usul. I do not play games.’

Paul glared at her, caught by the odd ferocity beneath her casual attitude.

‘He was not worthy, Usul,’ Chani said. ‘I’d not disturb your meditations with the likes of him.’ She moved closer, looking at him out of the corners of her eyes, dropping her voice so that only he might hear. ‘And, beloved, when it’s learned that a challenger may face me and be brought to shameful death by Muad’Dib’s woman, there’ll be fewer challengers.’
