So, I decided to not go with that rewrite. I kinda realized that I'm not comfortable with writing a dark!Harry that's also Tom Riddle, so instead of changing the plot so drastically, I'm just going to work a bit on covering up the plot holes in the previous chapters of the original plotline and refining the chapters.
The first rewritten chapter is already up, under the new story, The Circle of Dimensions. Please go check it out!
Thanks to everyone who reviewed!
