It'll be a lot of work I think! Not sure.

I tried to run the demo but wouldn't work as the templates you are using
seem to be outdated to my version which is A7..

I had a look at your model and I noticed that she hasn't got a full skeleton. Just seperate arms,legs etc.
I haven't done bone manipulation so I couldn't tell you how to rotate the
bones to match.. All I know is the simpliest way is to make sure you have
the model facing East in the top view..

Maybe somebody in the Editor's forum can help you with that part.

Otherwise you may have to search through every script and change a lot.

No point asking in the forums because very very few use the default templates.
You could try thought

Good luck and I hope you figure it out..
