Hi there. I don't know of any communities matching the characteristics you have outlined, especially when you specify the local "hermit" will then go to their own bishop and seek to be professed and consecrated. No, this is not the way the canon actually works. If a community, or rather, a laura (a gathering or colony of hermits which does not rise to the level of a juridical community) is to be established, it needs to be with those who are already publicly professed. Lauras are established for the support of those who have already been granted canonical standing. Neither are they to be established as houses of formation. (Hermits belonging to the laura may, if capable, serve to mentor persons seeking to be professed and consecrated, but the laura itself is not established as a house of formation.) I am not going to go into the problems of jurisdiction here except to say that it seems to me that this would be complicated if one belongs to a community with superior and statutes in one place, and has one's vow of obedience, etc., in the hands of one's local ordinary.
About twenty years ago I heard of such a community that attempted to use c 603 in this way. Those who signed up went running around in Carthusian habits and sought (or were told to seek) to be professed by their own bishops, so it must have been under c 603, since there is no other canon that might even be considered for such use. I don't know if this specific group still exists, but I believe it might have been a forerunner of the International Federation of Saint Bruno (St Bruno Lay Contemplatives) --- not sure of that, though. I do know that the Carthusians are very protective of those who can wear a Carthusian habit or use the Carthusian name, so if someone was doing those kinds of things with the habit, name, etc, the Carthusians themselves might have come down on the group. Bishops in individual dioceses who understand the history and nature of c 603 are very unlikely to be open to professing such persons under this canon.
