As a long-time husband and parent:
I don’t think it’s a good idea. You’re talking about being divided, not in tastes, preferences, favorite movies or whatever, but in the central thing that tells you what truth is, what marriage is, what salvation is, and how you live that out week after week. Will she pray with you before icons? Go to Liturgy with you? Go to confession before a priest? That says tons to children about whether what you believe is worth paying attention to.
In choosing a Protestant bride who will not convert, you’re saying that simply being married to someone is more important than the truth of the Faith and necessity of following it.
