I ~~am sure~~ hope somebody™ already thought of this. Feel free to advertise your project here.

Somebody should take document type conversion from Pandoc and version control from Git

And build a frontend around it
Well every one already recommended latex or markdown.
I would also recommend typst, it's a modern latex alternative easy to make templates and a markdown like syntax, none of all the backslash keywords that I somehow always forget.
Uhhh typst looks hot, that one I need to give a spin, thanks!
I made a template a while back when I had to make report, since I had a professor that disliked the markdown look of previous ones.
A bit of a learning curve, but once you get the hang of it, you make a few templates and write on them just like markdown with custom alias and whatnot.
