Hacking Disney Walkie Talkies into QRP ham radios.

I started a new project recently to determine if I could hack a Disney walkie-talkie into a QRP set. At first blush, it looks kind of simple, like maybe even a crystal replacement would do the trick.

Has anyone tried this? Is there a reason it specifically won't work?

Here are two pictures of the circuit board. The front looks simple enough. the back-side on the other hand... nothing by sm caps and resistors and transistors.
