What do you do with all the third-party software if you tear Java out of Android? I guess you could have a cross-compiler to <other-language> and run it automatically on install, with an option to run it at development time. But that means you need to also re-implement the entire Java SDK in <other-language>, not to mention the entire Android SDK. Wowzer. Big project. But you're right, it seems possible.
