That's why I'm asking for your opinion, TO WRITE A STORY THAT WOULD BE LOVED BY ALL CHILDREN.
This is a rough sketch of ideas, I won't start outlining the story before having your feedback.

Fair play for wanting to give this a go, but there's a lot to think about when you do.

I think if you're going to write a children's story then you would be best placed targeting a specific age group. Your ideas aimed at 8-18 is too broad I feel. 
And I know it's fair to say that adults will still read books for children, but if your target audience is children, then keep it to an 8-12 age range (OR SMALLER*). If you target 8-18 year olds, that's 10 years which is developmentally a big gap. You have to be writing it in a way for 8 year olds to get something from it and then at the same time, 18 year olds have to be getting something from it too. 

*Children's books also tend to be aimed at much smaller/specific age ranges, because you also have to be thinking about how reading abilities can differ so much from actual ages. For example, you will find books grouped for children between 5-7, 7-9, 9-11, 11-13 etc. 
You might get 7 year olds who read like 9 year olds and 9 year olds who have a reading level of a 7 year old, but they still have to be interested in the subject matter appropriate to them. 

I'd also read a lot of what children are reading. I'm in the UK and know for a fact David Walliams, Greg James, David Baddiel, Ben Miller are big at the moment (I wish I knew more current female authors at the moment in the UK but I don't I'm afraid), but a quick search on Amazon "children's books 7-9 or 9-11 or whatever" will give you an idea of what they're reading, and how they're written in a way that they can enjoy independently or being read to them at bed time.

Good luck!

Seconding EnhancedBeing's thoughts on making sure that the reading age is less broad.

You need to ensure that you're not just catering to the children that are reading, but also to the adults who are buying or recommending these books (for younger audiences). I wouldn't even consider pointing out a book for my 8-year-old if the recommended age range is 8-18 because it doesn't give me any indication of what reading age it's aimed at. Parents will have a rough idea at what level their kids are able to understand texts and it makes a massive impact on what is appropriate. If you have a child that isn't gifted at reading, you may as well throw your cash down the drain if the book is full of 'difficult' words that will instantly deter them from continuing beyond the first page. Sentence structure also varies greatly between 8-18 with shorter, snappier sentences being preferred for a younger audience.
