I don't mean to advocate anything but if there is an area without fully functioning Orthodox parish or without local Orthodox priest who actually live in the midst of his parishioners why would it be a total disaster if some priest wanted to set up a WR parish in that kind of area?
Who would this priest be? If there's no one to serve the existing small group of Orthodox, shall we bring in a new priest to serve an even smaller group of people rather than ministering to the needs of those already there? Would seem like terrible mismanagement, no?
Now that I think about it:
You could bring in maybe one traveling ROCOR WR priest to start out with, and see how it does. Maybe just in Oslo, Bergen, and/or Trondhjem to start with.
A lot of these parishes around the country don't have a permanent priest, so I really don't see how it would "hurt" Orthodoxy in the areas in anyway to have a change of Rite. It obviously doesn't (and shouldn't) need to be every congregation, but maybe just one or two. If anything, maybe Western Rite will make people feel a little more familiar (in a sense) to experience it.
But I'm no expert.
