Even if implicit remoting did work, you wouldn’t be able to do what you’re describing. The resource modules have to exist on the system before the LCM will start processing the configuration, and before the DSC module will start to compile a configuration as well.
That said, I think the only thing you’d need to be aware of is that DSC resources, by default, run as LocalSystem. This means they’d be authenticating using the machine’s computer account, in an Active Directory environment. In PowerShell v5, there is a common DSC property called PsDscRunAsCredential , which you can use to get a particular resource to run as something else. I haven’t tested whether that allows for direct connections to other machines without using a -Credential parameter, but it might work.
