NERDYBASTARD'S PROFILE

So, I started to try out battle systems for RPG Maker VX Ace, and I immeditally fell in love with the Tankentai Battle System. It has mostly everything I need for my game, and is just a gift for the heavens. That being said, I have some ideas for my game that I worry won't be able to be done with the system, so I thought it'd be good to get some help/feedback for my n00bish questions.

First off, I'm planning on my game to have a Mario RPG style to battles. What I mean by this, is that the battles will be sideways, and when attacking, multiple options for attacks pop up, and then to pull off the attack successfully you have to complete a sort of quick time-based mini-game of sorts (Something like this: http://rpgmaker.net/games/2205/MHBS/). I don't know if this is capable in the system though, and if it is, how would it be pulled off? Scripting?

Second off, the battlers are a bit too tiny for my liking. Thus, I was wondering if there was any way to change the size. Every time I've tried so far, I've just broken the system, because I have no idea what I'm doing to be honest.

So yeah, any help would be great, as I'm sort of stuck at the moment.
