I'm have 6000+ mature coins now in staking, as well as 6000+ still unmature coins

Here is my step:

1: create a new Z wallet address
2: send the 6000 coins to the Z wallet
3: send them back to my public R wallet

Here is the problem:

if they will be counted into the staking when the unmature 6000 coins got mature? 
or I need to do the 3 steps again ?
