Yes, this is certainly possible. Migrations are just python scripts that follow a specific protocol/api that is detailed in the excellent django documentation. You can insert your own hand crafted migrations to handle many cases that can cater for a variety of use cases.
i would suggest though an alternative and easier approach. add a new field with a different name and change your code accordingly. once the current field is no longer of use, remove it.
