Hey, you could always do what I'm doing
I'm remastering my old story (from scratch), and although once I post it here some of the old readers will recognize some of the events that are going to happen before I post them, it's gonna have a heck of a lot of changes too
I personally think it would be quite interesting to see how different this story would be if you remastered it with the writing skills you have now. I mean, you'd want to change some things that you thought weren't so good naturally, but when you've got a base story this good, why waste it?
I'm probably not making any sense at all, so I'll shut up now
