The only way to do it is to phrase it like “Recip I loved your letter so much. I feel like I could write all of your prompts! (There may or may not be a draft document open already...)” or something.

If the recip hates the fic they can politely ignore it/talk around it, and if they loved it they can be like omg!!!!! please write me all the things!!!!!

Please don't say the draft document thing either, unless you are really truly sure you'll follow through.
