Connecting multiple RequireJS or multiple configurations?

Question

RequireJS

Good day to all.
This is the question:
Connecting multiple RequireJS or multiple configurations.
The fact is that you need to write a widget that will be connected to sites that already have RequireJS and its own configuration, indicating, for example, the parameter: path - the path to the scripts, etc.
There is no way to change what is there, it turns out just through Define to connect your scripts from a remote server without your requirejs.config ?
