Do you need to even use a configuration file? hostapd control interface
can be used to dynamically add and remove interfaces, set configuration
parameters for those interfaces, and enable/disable interfaces. That's
what I would be using if there is any need for dynamic operations
instead of trying to stop and restart the process.

It would be interesting to see if something could be added to the
upstream version to get more functionality in this area.. I'm pretty
sure there are multiple implementations doing something like this, but
not very promising contributions to add that into hostap.git yet.
