I'm not sure (I simply do not know) if the RN difference would level things out though.

No I don't think so. My experience so far with a 183mm compared to both a KAF16200 6 micron and 16803 9 micron (I did have a KAF8300 a few times as well) is that its more sensitive especially in Ha and O111 and S11.
The KAF sensors are probably somewhere like 40% QE or less for Ha whereas the 183 is up around 70%.
Its definitely faster than the CCDs despite smaller pixels.
