As of the current version, it is but the setup is more complex than MZ which has the plugin command manager for easy setup. In MV you'll need to use a few plugin commands or script calls before starting the game.
For long sequences it can get very complex very quickly when using MV.
You can reposition it, use conditional branch with the switch it activates and if you fail you can apply a duration penalty
QTE will tell the event interpreter to "Wait" whilst the QTE is running. This is basically the same as an event running as is the case for normal events so yes you can use QTE during the TBS but for TBS attacks, you will need scene motions or map motions extensions for the relevant scenes.
