I think it would be nice for a doe to finally settle down and let Woundwort be somewhat happy. The TV version of Woundwort is much less scary for the sake of being scary. Your OC is very cute as well!
But there's nothing wrong with shipping characters. For one, rabbits aren't huge on monogamy (unless they're pets and there's only two of them), so even if a character already has a mate, it's not unreasonable for them to mate with another. My favourite OC Elowen mates with Acorn from the bookverse. There was nothing really romantic about the ship; they just had a few litters together.
Ship your characters with whoever you want!
