rear number plate mount

As winters fast approaching im wanting to tackle a few jobs while bike will be garaged for a few months and im wanting to do a way with the  bulky no plate mountings and im wondering what other members have done as the undertray and no plate looks like one moulded piece? is there a mod you can get to achieve this? or what way would you go about this.As i dont really want to start cutting the original undertray and fuck the job totally. oh and its a gen 1
