If you want to use IP addresses but not URLs/Domain(s) to reach to your web applications, then URL Maps cannot help to implement your design, as URL map forwards the request to the correct backend service using host values (example.com) and path values (/path) in the destination URL.

That being said, you can add one more Target Proxy to your LB resources to route incoming requests directly to the desired backend services. This will allow you to keep your minimum number of instances as one VM.
