It should be possible; previously I've changed an existing APK's package name without access to the source.

However, you will probably need (and I don't have any more specific guides to hand):

• a hex editor
• a guide to the APK file format
• a way of calculating the APK checksum

You need to unzip the APK, alter the (binary-packed) AndroidManifest.xml, alter the checksum in the resources.arsc (I think) and then re-zip the APK.

Actually, in searching for a couple of these resources, I came across apktool, which sounds promising.
