Realism is a Thing

Okay, so I may have been overly optimistic about my "five chapters in three months" goal in the last post. It came from a place of honesty, based on the progress I had made in one day and my eagerness, but not accounting for the long down times between writing sessions. Rewriting the initial chapters of TToTS is a *HUGE* undertaking, with the Prologue already clocking in at 8,700 words--twice the original--with this being the... third rewrite attempt? So while that is more of a long-term goal (and I do still intend to finish it this year, preferably this half), I have more manageable shorter-term goals:

1. Finish Flight of the Valkyrie. I have spread myself too thin, and I need to finish something. I am proof-reading the final chapter now, with only the epilogue left after that (and some bonus chapters after that, if/when I feel like it).
2. Continue The Tale of Two Sisters. The truth is, if I force myself to only work on the rewrite, I simply won't want to write. Chapter 21 is almost written, and I plan to continue passively pushing forward while working on my other tasks.
3. I started another story. Yeah. Not a goal, but I wrote about 2,500 words setting up a "Two Sisters universe" spin-off, focusing entirely on the Mane Six, set post-Season 9, pre-time-skip. I don't expect I will work on it much, but it's there, and I think it will be a cool story; and it will let me play more with the canon characters once FotV ends, focusing on Rainbow Dash and more time-travel-esque shenanigans. Actually, the main problem with this story is that it will spoil Ask-Pink-Pony lore that the story hasn't reached yet (I mean, it hasn't reached any story yet), so it's going to be tough to release, as I've only teased aspects of APP's plot in my fics before.

I've mentioned this before, but I wanted to get some feedback if at all possible. I have plans to adapt The Tale of Two Sisters into an original work of fiction. While the world and the instigating factors will remain the same (old-gods, castle escape, sisters raised by wizard), the actual progression of the story will be structured more like a Zelda game, with "areas" and "bosses" to progress through, rather than the current flow of consciousness. So my question is: Would you still be interested in reading my period adventure vaguely based on TToTS (without the time-travel nonsense to account for MLP canon) if it wasn't connected to MLP, and if so, would it still need to be anthro for you to be interested? I've not decided exactly on the races yet myself, whether mythological or human. Let me know below! To be clear, it won't replace TToTS, and I probably wouldn't focus on it until after TToTS is done.
