I'm wondering if there would be a performance or noise boost or penalty if i were to use an impeller from a DDC1 (black impeller, really large intake) into any of the DDC3 offerings (blue impeller, small intake) currently on the market. Has anyone tried that? OR are the impellers incompatible between DDC series?

Good question, I have no clue. I would love to find out, my DDC is louder than all of the rest my system, I can often hear it from the other side of my house. I would love to know if there is an upgrade to eliminated this.
My mcp355 with a res top is pretty close to silent with all 900rpm fans... Not sure why yours is so loud. I would suggest rather than screwing with the pump and potentially ruining it, sell it on the used forums, and buy a vario D5 that you can reduce the pumps rpm's with a knob on the pump itself.
