), basically swapping the front thermostat housing with the rear heater hose port, can I connect the turbo's cooling line to the heater hose port (now at the front of the engine) and connect the heater core to the turbo's outlet?
That would function but may not function well for two reasons. Flow out of the back of the head is necessary when the thermostat is closed so that the thermostat sees current coolant temperature flowing past it. Secondarily, the flow through the heater core would be diminished and may not be adequate in cold weather.
Consider taking the flow for the turbo from the front of the engine as you have it drawn, but returning to the mixing manifold at the water pump Inlet through a drilled hole and added nipple.

Ok, but then where do I connect the heater core? Feed from thermostat housing and return to the mixing manifold again?
