I'm guessing that using this mode with a HA filter still means only the red cells will register the image as the HA filter will block blue and green?

Robin RAW is RAW - that is you get the pixel values, colour is synthesised from those raw values via a debayer algorithm.
All maxim is doing when you choose monochorme is taking a 2x2 grid and summing the pixel values to give one value for the larger "pixel". This is not the same as binning at the hardware level on a CCD. You will have (with the Ha filter in line) a sum of RGGB with only signal in the R cell To cut a long story short there will be no improvement in S/N ratio using Maxim 2x2 mono.
