I did think of that, and will be trying it, but I don't know if it will work and remember someone saying about clone and touching some file.
Two things:
1. For backup (and clone) I'm using the "Win32DiskImager", latest version (1.0.0 - 2017) have option to don't save empty parts. So for cloning, I made a backup (image), then write the image to another card. That is complicated in case of big cards with a lot of data...
2. I prefer to use small (high speed) SD card for system (LE), and for any other data a big USB-stick. It's a huge advantage, when I need to reinstall the LE and don't need to take care about all other files, downloads, music, video... because is stored in the USB-stick...
