i don,t think anybody would pick u up on a double sided hub , it,s not a performance thing , u could use a cable for the brake , would save the hassle of changing wheels and keep it more orig. personally , it doesn,t take mutch practice to get to know the right side change , i,ve raced l and r bikes on the same day , but it,s better to ride all left or all right hand on the same day , also u can get the case bored and a boss welded on to take the seal ect ,
