In general, you speak correctly, but with incomprehensible and unnecessary complications, everything is much simpler and faster:
1) You can perform this procedure for 1 time, there is no need to repeat something until you get a new stake and automatically split the block. To do this, in the control of coins, click "Select All" and send them to any of your addresses.
2) there is no restriction on the main address - you can send all your coins to ANY YOUR PERSONAL ADDRESS - main or any other inside your wallet. The result is not affected in any way.
But the coins will need to get mature again to stake?
