Hmm... True. Although I will point out that out of the main Byzantine traditions, it does seem that the Ruthenian Church is certainly the easiest of the Eastern Catholic Churches one can join without canonically converting right away. I mean, sure, if you become a parishioner, and have been there long enough, you'd have to convert your Rite to Byzantine Catholic eventually, but at least you can fully participate in the common Liturgical Mysteries if you so chose to. It's the more advanced ones like marriage, and ordination, as well as funerals that you might run into problems. Other than that, just as long as you feel comfortable with the tradition, by all means, be in the communion line, go to the icon of Jesus for confession, be anointed during Mirovanije, whatever.
