Are you referring only to the comparatively trivial fact that you wouldn't celebrate her feast day on the Roman calendar, or recognize her canonical status as a saint of the Latin Church?
Or is there some obvious reason why you would not consider Joan to be among the holy ones in Heaven (traditionally the primary meaning of the word "saint"), or to have lived a holy life on earth?
The fact that we have partially differing martyrologies is no reason, by my lights, to preclude our considering at least some of one another's saints to be true friends of Christ and worthy role models. As a Catholic, I can and do honor as saints holy men and women in the Eastern Orthodox (not just Eastern Catholic) tradition, and I hope that if I were Orthodox I would not refuse to consider as saints holy men and women in the Western tradition.
For a number of years I included a Russian Orthodox spiritual writer in my personal litany of saints. I have no problem saying that I personally consider him a saint. I could be wrong -- I don't know for certain he is in Heaven (or even whether the Russian Orthodox Church itself regards him as an "official" saint). But I would never say that I "obviously" wouldn't consider him a saint, as if it went without saying.
BTW, do Orthodox Christians really use the word "Orthodox" as a noun, as in "I'm an Orthodox" or "As an Orthodox"? I understand that to insist on the adjectival form can be a little awkward; "I'm Orthodox" (adj) works fine, but "As an Orthodox Christian" gets a little clunky. (Perhaps "Being Orthodox"?) Anyway, it sounds much better to me as an adjective.
Frankly, I'm not even fond of the nounification of "Catholic" ("I'm a Catholic"), though in colloquial usage it enjoys overwhelming acceptance. Properly speaking, it would be better to say "I'm Catholic" or "a Catholic Christians" or "I belong to the Catholic Church," but there's no sense making a big deal about it.
