Sure you can! Most of the parts Losi has them, from de dirt modified car. Front bumper, body mounts, etc. The only thing problematic could be the two speed, but if the OFNA does not fit you can try the Thunder Tiger two speed. It is very small and I've seen it in a RC8 that uses a center diff about the same size as the Losi. Another consideration would be the wheelbase since the buggy is smaller than the truggy you have to verify that it isn't to small a wheelbase. I would use a truggy chassis for stability but that doesn't mean that a buggy would do great.
