Yes, you could do that.

Not sure why you would want to do that though. The MCP600 will probably be running somewhat towards the end of its PQ curve and not be contributing much at all. It'd make sense if the Iwaki's in series were pushing less than, say, 7LPM through your system, but if the Iwaki's by themselves are pushing above that, I'd be tempted to give the MCP600 a miss as it'd add so little to the flow rates to make any appreciable difference to the waterblock's performance, but will be dumping extra heat into the loop (not that pump heat is much of an issue with 4 double heater-cores).

Just a single Iwaki MD30-RZ would serve you better in all scenarios, and dump less heat into the water as well.
