Unfortunately, it appears that on the A320 seeing ILS raw data is difficult with an FMS non-precision approach set up:

If they do press the LS pushbutton after loading an approach with vertical guidance, they will get a flashing amber V/DEV message on the PFD to highlight the incompatible selection.
Another workaround I'm told would be to put the ILS 28R in the secondary flight plan and toggle to it on final but that opens up a can of worms with a possibly different missed approach and non-standard procedure.

I don't think the ILS being tuned and displayed or the FMS approach would, or could have, made the slightest difference. Once locked into the the visual picture, the crew wasn't going to change. What's surprising is they did NOT go around when they believed the runway was blocked.
Agreed, the biggest raw data cue in this case should be visual, a bright flashing 'X' on the closed runway 28L and ALSF-II approach lights on 28R.
