I don't think that sounds odd at all. Most of us are bi-ritual by necessity. I think the concern is with spiritual formation - what we do primarily is one rite (at home prayers) as each cursus of a liturgical tradition was developed so that it trains the Christian who follows it.

So - I'm Western rite normally, but often participate in both Arabo-Byzantine, Helleno-Byzantine, and Slavo-Byzantine worship (and, there is enough difference between those, so that going from Greek to Slavic is surely 'bi-ritual'.) Even more with the Old Rite such as they have in Erie, PA - which is very beautiful.

Otherwise, I think the whole paradigm of the rites being different enough so to require a term 'bi-ritual' is more native to late Roman Catholic thought, and not really part of our Orthodox understanding of worship. An Orthodox Christian simply in the worship of the local church - it is all the Orthodox ritual (whether Chrysostoma, Gregorian, etc.) In the Russian Church, we have had clergy serving multiple rites for the past two centuries - but without the idea that they were 'bi-ritual' (sometimes we say so as a concession to weakness) - a Russian Orthodox priest simply celebrates those rites of the Russian church: whether the New Rite, Old Rite, or Western rite (all have been approved by the Holy Synod.)
