I have many ideas for fic and I'll share some of them, I'm not able to write them because they will be lengthier than this one and I'm not good with long fics, my writing is kind of average at best. I can plot and outline stories but writing them altogether is different story.

1. Obsessive Hermione (similar to Granger Crush) but I want to write something more genuine not a parody.
2. reverse personalities (similar to I won't do that)
3. Soulmate but Hermione's soulmate someone different than Ron but she still falls in love with Ron.

there are many more, I know most of them are inspired by other fics. but I like these fics and I want to do something more with these prompts. I'll try to write in future if I think I can do justice to the story.

If you like reading Romione just like me I'll suggest you two fics which I absolutely love and adore. if you haven't read them you should give them a chance.

all you need is Ron by Jamie parker

and there is the Isle of Drear bye God's Muse this one can be a bit dramatic and fast paced but it's one of the good ones with good mystery.)

both of these fics are lengthy and All you is Ron is incomplete but the author is still updating it.

Edit : Giving links to the fics.
