Feedback on Idea for MG Novel

This idea sort of came to me. I wanted to know if you guys felt it would work as an idea for a middle grade novel. Also, the title is the working title.

After Amelia Earhart and her navigator Fred Noonan's mysterious disappearance, many theories arose about what happened. In my WIP, ALIVE AND WELL IN DIMENSION WOMAN, Amelia and Fred didn't die. The plane didn't crash. Through a series of clouds, the two are transported into an alternate dimension.

The dimension is filled with strong, powerful, women, with important careers. At first, Amelia is impressed with this dimension, until she discovers the oppression of men. They can't own property or vote. Boys usually don't go to school, while their sisters do. Husbands are expected to do as their wives say and be obedient.

Amelia meets a thirteen year old boy named Jonathan, with a desire to fly. Of course, in this dimension, men just don't fly. It isn't done. Amelia risks her life to help him acheive his dream. When she takes him under her wing and teaches him how to fly, they're in more trouble than they ever would've thought.

This is basically the starts of the plot. Please tell me what you think.

Yeah, it's the working title, which always turn out to be horrible. I'm excited about this story, but it's going to take a lot of research. I usually don't have to research that much for a novel, seeing as they usually take place in the present, at a school, with people my age.

Well, I was expanding more on the idea. What I have so far is that the president (verging on dictator) finds out Amelia is working with Jonathan. She thinks Jonathan is an innocent young boy and sends Amelia off to jail. Jonathan refuses to give up and goes on his first solo flight across town, by the prison. This attracts attention and people are shocked a male drove the plane. It becomes a media circus and Jonathan starts a men's movement, much like the suffragist movement. It's basically ignored by the political leaders and they don't free Amelia out of jail, but they're still determined. It would end on a note that the movement has started, leaving hope that they'll movement will eventually mirror our women's movement and stuff. (Gotta leave an opportunity for a sequel..he he)

I was thinking for the president/villian person that maybe she was a women's right activist, fed up with our dimension, who wanted women to rule, and so she, along with some other women, established such a place, but I don't know how I'd make that work, since it's an alternate dimension.
