Im sorry but I fail to see how that wouldnt be one of the better sides on the international circuit ATM , 'would beat any other international side' , is a bit over the top.
But the fact most of them have been succesful at the top level for a long period of time , some of them extremely succesfuly , indicates they would make a pretty solid unit in both forms of the game.
The bowling would be light on by test standards , but the batting phenomenal.
