Magna Carta Battle System [Request]

Hello everyone!
I was playing Magna Carta game for PS2 and I liked the type of the battle.
When you start the battle, you maybe think that is impossible to play, but
is a matter of time to catch all game rules.

So, I've wanted this battle on my RPG Maker Game, especially at RMVX.
Can anyone help me with this?

1. First, you have to wait for the corner bar load, where is an P (of player). When the bar is loaded, according to your agility, is your time to attack.
2. In the battle field, you have a "field of view", when you approach an enemy and your bar is loaded, you change or not the attack at that turn.
3. You can change the atual player in the battle, for example:
  If you are playing with Calintz, and in your party have more 2 players, pressing the button L1 ou R1
  you'd change the battler. Unless you want play with only Calintz, the 2 more players will do nothing.
4. Soon after choice the attack for at turn, the game will show a sequence of button that you need to press. Of course if you lose the sequence, your attack will not have damage effect. But is an simple sequence, 3 buttons only.
5. You can use itens in the battle field too. To this you have to press triangle (On PS2), and then you will be in the itens menu.
6. I don't think that is impossible to make this in RPG Maker scripts. I try to learn, but is a little bit complicated. I have a notion of scripts.
The bar only will load if you is not walking. This rule is for the monster and to the player.

Remembering, this is for RMVX.
I Hope that someone help me!

Wow, thank you, this will help to the encounter system.
I've make a system like Magna Carta through events, but isn't the same thing as script.
Sorry I don't know how to give you a Rep+.
