You might be running out of faces as there are ~120,000 faces in the facepack. If you use NewGAN Manager v1.2.0 you assign duplicates which should solve the issue if it indeed is running out of images.
The views weren't designed for FM21 Touch and I'm not sure how you can make them work in FM Touch. If you somehow figure out a way though, it should work, you would just need to copy the facepack and config over to the FM Touchg graphics folder.
Nothing has been planned so far. It's not out of the question either, there just haven't been to many specific requests that would warrant a bigger pack.
