I think I answered this in another thread. The trick is to decompile the dcp file using dcptool. Change the camera descriptor in the resulting xml file to the correct descriptor for the R6 and recompile it to a new dcp file. It will now work for the new camera. It won't be perfect but since these are vsco filters probably it will be good enough as they are usually quite extreme so subtle differences in sensor behavior won't do much.
