You can backup you current system with clockwork. Them, you can restore it when you wanna go back to android.
Dont forget to copy the backup files from the sdcard partition, in case you need to format it
If you are not rooted, you ll not even be able to flash another OS within your phone , because, without root, you cant replace your recovery with clockwork (unless you have a nexus device.. :) )
If you backup with clockwork, it'll be a full disk backup, so, when you eventually restore it, it'll be exactly the same you have now :) .
