Renaming config files with Visual Studio setup project

Question

My applications have a handful of config files, each one particular to the machine it's being deployed to (dev, production, etc.) I'm wanting to add them to the setup project, use radio buttons to select one and then have a script (or maybe custom action?) rename the selected files to connectionStrings.config, settings.config, etc.

Is this feasible/possible with a setup project?

To give you an idea, my configs might look like this:

DEV connectionStrings.config
PROD connectionStrings.config

After the user chooses DEV or PROD in the installer radiobutton UI, I would like the chosen config to be renamed to

connectionStrings.config

Considering it's a VS setup project, I have a feeling I'm asking for way too much and that I will get an interesting response as most setup project questions do :)
