Yeh,
i think the second sentence sounds a little pushy, it sounds like you could be complaining. However, if you rephrased it as:

I hope that you get better soon, or I hope you will feel better, or I hope your recovery comes quickly.

"I wish you would" could be interpreted in such a manner as you are annoyed that the person hasn't healed quickly enough (almost like an inconvenience to you).
