Dream on! The whole reason that the Europeans won't approve approaches using GPS is so that they can charge us for the Galileo-based service when is is eventually available. If they approved GPS then no-one would buy the new, more expensive units when they become available.
The Galileo units will undoubtedly be much more expensive because (a) the manufacturers will need to pay a big licencing fee to Galileo and (b) there will not be anything like the volume of business that there is for GPS.
I wonder how long it will take the CAA (or EASA, or whoever is in charge at the time) to approve approaches using Galileo? You can be sure that it won't be long, as they will be wanting to get at least some of the the investment in Galileo back.
