The Expansion port is already implemented in the widgetboard but the code to transfer the signals to the Nexys4 is not in yet.
The IEC bus would need to be connected to the PMOD connector of the Nexys or some of the free databus lines on the widget board
and would need to be inserted into the code as well.
All the code (for the ARM on the widget board, or the VHDL code for the Nexys), is open-source and already available !
If you are interested to implement one of those, we would be happy to support you, but we concentrate on the R2 board and to keep the Bitstream convenient between the R2, the MEGAphone and the Nexys4DDR.
But anyway: i move your post to the Nexys4 section...
In case you meant the internal floppy instead of the IEC drive port for 1541s etc, then on much the same basis, this would be possible with a funny PMOD adapter.
