It seems to me like the cage size is actually quite appropriate for your hedgehog. Hedgehogs need lots of room to run around so the bigger the cage the better.
How do you know she is only using half the cage?
What kind of bedding are you using? If you're using shavings I can see why cleaning would be a pain. Is there any particular reason why cleaning the cage is so difficult?
I use fabric liners, and my cage is fairly large and I don't have any issues with cleaning, in fact it's super easy.

As for the flying saucer wheels, they are acceptable wheels. The only concern would be joint issues caused from the legs crossing over when hedgehogs run. That being said, some people on here still use them.
What kind of wheel do you currently have in your cage?
