Yes, Wayland is in GRM control and is a Fortress World serving as a Hostile-Climate Training Center for the Clone Armies of the GRM. Something to keep in mind, however, is that beyond 19BBY things no longer line up, and much of what is canon will simply not happen. So, this means that Palpatine never established any form of presence there in terms of research bases.
