Those bottom - back of the headstock tuner - holes will be covered by the Kluson style. One VERY important point. Those bushing washers on the top of the headstock make be stuck to the finish and if you aren't careful removing them, you could pull off the finish around the hole. A touch of heat usually frees them but fast and carefully- so you don't end up melting the finish.
I don't think that a Rickenbacker dealer would do this conversion because it would probably void warranty because you are modifying a stock guitar with something that the guitar wasn't originally designed for -for 2008.
I'm about to do another conversion on a 360 to Kluson style.
I can do this for you - but If I were you, I would start by carefully removing one of the machine heads and seeing if the washers are stuck and if there is an impression that shows enough to actually do the finishing work process.
