JKnife - let's be clear here - you don't have a better IFR capability, you just have better kit (twin VOR/DME) I suspect instead of the one that we make do with. The better kit doesn't get you to a hold or down an ILS any better or allow you to utilise a lower DH/MDH so where is the better capability.
As for IMC letdowns over water to vessels or coastlines - I can only assume you haven't tried to use the FLIR/TV in these conditions because neither can see in cloud so not having a full radar picture can be a problem - vis trying to turn through 180 when faced with an onshore wind and a coastal letdown into a bay...how do you clear the area you are about to turn into?
Can you couple the AFCS to the nav kit and fly searches in autopilot mode whilst having a the FLIR autoscan for survivors with the ability to detect a head in the water from 1000m @ 500'? That is modern SAR capability.
