I like to imagine Curtis dumping the band after Closer and working with people like Hal Wilner and Vangelis in Blade Runner mode. He would have made something like 'Tilt' a decade earlier than Walker managed it.
Somehow i couldn't picture him raving in The Hacienda with 'Ooky" and Barney or swanning over to Ibiza and telling us how many pills he's popped and how "mad for it" he was like the afforementioned aeging hedonists.
Maybe he would have headed up to Edinburgh with Mark E Smith and avoided all the Madchester thing.
