For my H2O, I would have to install 4.9.11341 and then I would install the new version without the OS. Then I would patch it and hope it works. I may do this given what others have said.
Not loading the OS is not what you are doing when you install just the KoboRoot.tgz. It doesn't include the kernel, but, it includes a lot of files that are effectively part of the OS. And, the risk of installing any of the new upgrade packages on the older devices is very low. In older firmware, it was a problem. But, the update script now does more checking of the contents of the "update" directory and only installs the files appropriate for the current device. Going the other way, using the Touch package on a Clara HD, might be a problem.

Also, updating over to much of a gap is probably not going to work. Updating a Touch running the factory firmware with 4.11.11980 isn't likely to work. But, letting the Touch update to the latest official release and then installing the Mark7 4.11.11980 package will.

And for the drivers and similar included in the KoboRoot.tgz that are different, it won't remove any that are needed. It will mean extra files that are never used are on the device and some aren't updated.
