The THN scripts are not that hard to work out. But they also control ship dealer hardpoints, NPC positions not to mention the way the player ships comes into the sequence. There is a camera rotation calculator you can use for camera positioning.
Yes you could just use already existing scripts and create the CMPs to suite. But if you ask me that could be as much work as creating a new one. And theres also the fact that you will still have the same old ships flying around.
If anyone is seriouse about taking this up. Ill be happy to give any advice on ruite positioning for ships, and adding new ships and engine effects.
