Question or more statment for USAR. With the current deployments and cross leveling of Soldiers.
CSM,
One of the things we used to do back when we returned from Desert Storm and we many attached Soldiers who would now be considered cross leveling was have units within the vicinity of them no matter wear they were in the country check in with them regularly or have them check with the units as well, it didn't matter if it was NG or USAR, we were all one at that time and had the connections and concerns for the SMs.
I don't know if that element of concern and cohesion still exists in today's mentality, but it worked 20+ years ago for the NG and USAR units and connectivity with the troops.
That may be something you as a CSM could put into the motions at the state level HQs and via the NGB as well to see if that type of workability could be a possibility again as it was just a few decades ago.
