i am not sure what you mean by "side loading" means to you.
to me.. that means able to load apps that are NOT on the Play market. Downloading an apk file and loading.
i guess you want to root it... back that apps and all its user data.. and restoring it on another device. you would use an app like Titanium Backup.
but I want to warn you....
that what I think might be an issue... the two devices are totally different.. and have different hardware and associated drivers (kernels).
the app may configure itself to work on your phone. and you back it up that way.
restoring it on a totally different device ...may not work to well...
if you have the KF rooted.. make sure you have it fully nandroid backup before you try this. just in case. :P good luck
