Yeah 'Better' is one of my favourite songs on an album filled with great songs so I wouldn't be mad if we got more Britney x BloodPop. As long as all the key people behind the scenes are involved like Mischke and Karen Kwak then they've got some room to play and experiment off the back of Glory. Sales and streaming are whatever for Britney these days so they should just get weird with it. Oh and I'm wondering whether this "special song" that @timothy_b mentioned is for a movie soundtrack perhaps? As long as it's not some hideous concept like a 'Baby' remake inspired by the 'Where Is The Love?' remake that the Black Eyed Peas did, because no-one wants that.
