No, in that setup, the small turbo would not help spool the big one very much at all, it is there mostly just for lower end power. Those big blocks in the exhaust and intake of the big turbo are doors/valves that open up once the big turbo is ready to spool or the small turbo has already spooled. The waste gates vent to atmosphere.
