Yes. I think it is not too late. I've moved to south in a middle of a project and I am happy with that choice. I think it is a big help for deployment.
The initialization of the south app can be done at any moment.

It's even mentioned in docs:

It's quite straight forward to start using South.
Just follow the installation instructions (don't forget to run syncdb at the end).
Then you can convert the app to south:
./manage.py convert_to_south myapp
Then you can make modifications to your model and do schemamigrations or even do datamigrations.
