mmmmh, that global overlay stuff needs some review; I mean, for write
operations I suspect some of the data consolidation should occur earlier
so that regular overlays can be injected as global.  Otherwise, global
overlays need to be specifically designed to work as such.  This does not
defeat their purpose, that is the capability of manipulating requests
before a database is selected, but does not work toward reducing code
duplication.

I'v ebeen playing with the chain overlay recently (see my fixes this week)
and it worked well alone.  There might be some isses in cooperating with
the syncrepl.  Did you try reversing the overlay stacking order?
