To make current images run on Lonrisun clones requires quite some more changes than just replacing the drivers.
First of all the way the new drivers are loaded has changed compared to the old drivers and for the Lonrisun drivers to load this has to be reverted.
Second you also lose all features only newer drivers have (gles menu animations, CI+, xbmc), so you have to remove everything using those too.
While you can easily just uninstall xbmc and the menu animation setup plugin, CI+ and the gles functionality itself is tied to the enigma2 binaries.
The only way to get rid of CI+ and gles (If present in your image) is to replace two enigma2 files with their counterpart from a Vu+ Duo (Not Duo²).
However, each and every update would break this again, that's why image modifier wrote the opkg-wrapper in order to take care that whenever enigma2 gets updated, the two files that need replacement get replaced with their same revision enigma2 files from Vu+ Duo.
That's simply too much to explain in some simple words.
Why not simply use one of the many pre-patched images in DW DOWNLOAD SECTION ?
