This is your underlying problem. From a normal perspective you are basically asking how you can do a man-in-the-middle attack on your own devices.

Yes you could potentially ask the phone to pull in configurations from more than 1 server (i.e. local server + remote server), but to do that you need authority to change the current provisioning setup. Since you don't have access to change the .cfg file on the server, you don't have that access.

The real question is why don't you have access to change/add the values that you need? If it is somebody else's server who refuses to grant you access, then why not simply request that they add the additional configuration options for you?

On the other hand, if the .cfg files are being generated by the server and you do not have/know how to modify them without causing bigger issues, that's a different story.

In either case though I would strongly suggest trying to solve the problem properly rather than hoping to find a loop hole in the way phones provision themselves and pull configurations. (I'm not saying you couldn't find SOME way of making it work the way you are asking, but you are much better off putting time/effort into solving the primary underlying problem rather than hacking unreliable efforts around it...)
