Yes an EGNOS based approach such as LPV or LNAV/VNAV would appear to offer the potential for Cat 1 limits without the need for the expense of the ILS ground installation. The downside is that aircraft would have to carry suitable equipment in order to use it, though I imagine that in time this will become the norm for commercial aircraft. I am not sure how the timing would work out for Stobart and CAX - for all I know they could already be planning for it.
Alderney appears to be the only UK airport publishing an LPV approach at present with a 300ft OCH though presumably other airports will follow suit. The procedures are more widely used already in continental Europe, mainly Germany and France but also Italy and Switzerland.
