Hmm, groping around in bad weather when you start off vaguely knowing where you are is a LOT different to being in the soup and trying to get out of it. Helicopters have a minimum speed for the stabilising surfaces to kick in, which is mostly around 45 knots, near 70-odd in a Dauphin, so hovering IMC is out.
We used to do ILSs at Belfast down to about 100 feet in our Beavers and I can assure you it is not fun. I certainly wouldn't like to do that in a helicopter.
