Founding a new WRO parish from scratch (as opposed to a mass conversion of an existing parish) is bound to be really, really difficult. Such a parish is highly unlikely to have much money or a very beautiful building; people who are generally attracted to traditional Western liturgical churches will be more likely to go Anglican or trad Catholic if these options are in range, as they are more likely to be firmly established. That leaves you with those who are specifically looking for Western Rite Orthodoxy, a tiny niche within a niche.
I have a little anecdote which doesn't necessarily prove anything, but since we're dealing with such a small pond, maybe it's worth sharing. My hometown has an annual festival centered around a famous monster movie filmed there, and all the local organizations put out tents for people to learn about them. The local continuing Anglican church (in the Diocese of Christ the King) had a booth and I approached the guys there. I told them I go to the local Orthodox church and one of them started talking about WRO, about which he was very knowledgeable- he had a copy of the missal put out by the AWRV and other material related to the Western Rite. But he was happy where he was, and felt that Western Rite Orthodoxy was a ghetto within Orthodoxy that was unlikely to ever get much respect or support. He specifically mentioned the Byzantine paraclesis inserted into the Mass as a sign that the Orthodox basically distrusted the Western tradition. I told him I felt the same way but, as an obscure layman, no one is ever likely to care what I think.
But other than that, like most (all?) continuing Anglicans, he regarded us as brothers and a real church, and had a lot of respect for our tradition. Now, I'm not saying we can completely reciprocate that feeling- the historical and doctrinal problems of Anglicanism are big- but I think with just a little more respect toward them and their tradition, it would not be hard to bring them to Orthodoxy.
