Can it? Does it run with root permissions? (Honest question, I don't know.) If it's bound by the OS permission system and doesn't have full root, it might be able to replace apps with another version that is signed by a different key (using the "programmatic app installing" permission). However, that would wipe the app data and break app updates. Not even adb can replace an app with one that is signed by a different key without data loss (adb install -r). And I'm sure a lot of developers ask for this feature.
