In overall structure, the PC is like a Bit — a storage element that connects to out and also feeds back to some combinational circuitry that creates the next input value for the storage element.

When you connect load=True in a Register, you have logically turned it into a DFF16.

You have the right idea about using 3 Mux16s to handle the control inputs.  You just need to get the Mux16s' inputs connected in the right sequence.
