Welcome, Cloud9! We hope you have fun in our playground.
You might want to check out the
Fanfic Archive if you haven't already. TOGOM is by far the most popular episode for rewrites; so many of them have been written over the years I wouldn't be surprised if your idea hasn't already been written.
Try looking under R for Wendy Richards.
She's written the majority of TOGOM rewrites, so if anyone's tackled it, she's your main bet.
I'm sure if it has been written, someone here will be able to point you in the right direction to find it.
