I understand what you are trying to say, but it gives the impression that Holy Orthodoxy is a big mish-mosh.
That’s not the case at all.
I would have said something like: “If you look in on the non-Roman Catholic Apostolic churches, remember there are more than just one type.”
But from my (Orthodox) perspective, I might have said this also:
“If you look in on the churches outside of Holy Orthodoxy, remember there are more than just one type.”
“For example, in around my neighborhood there’s Greek Catholic and Roman Catholic, and Ethiopian Tewahedo Church; elsewhere in the city, the Armenian Apostolic Church, Assyrian Church of the East, and a Coptic Church.”
I am just pointing this out because everyone has a different perspective, and I just lump the Roman Catholic church with those other non-Orthodox churches listed here and it it looks like your church is part of a big mish-mosh!
Of course, that’s not fair either, I realize that.

I am just stating that we can unintentionally make the situation look different than it really is.
For purposes of clarification, the Greek Orthodox, Serbian Orthodox, Bulgarian Orthodox, Romanian Orthodox, Russian Orthodox and Antiochian Orthodox are the same religion, essentially the same church embracing the same theology and following the same body of Canon law. We call it Holy Orthodoxy and those national designations are actually synods within the one church, much like the CECC/CCCB, the USCCB [USA], the CEM [Mexico], the CEE [Spain], CEI [Italy] and the CBCEW [England/Wales] in the Latin Catholic church.
