Orange caps for International Matches too?

One of the few things that I like about the IPL is their method of issuing orange and purple caps for the tournament's highest run-getter and best bowler, respectively. I am wondering if this can be introduced for international matches. I am not recommending this for tournaments but for every team. This mean that every team can cap and mark-out its most successful bowler, its highest run-getter for the season and may be the Most Valuable Player or MVP too. The MVP system has been used in professional basketball and many other American sports for a long time. This does not do much in terms of making the game more interesting but is just a small change that can seep into the present system and add some value-addition for the TV-watching, cricket audience.
