I'd be worried about that, if it weren't for the fact that no adaption using the ship has ever really given Bernard his own character outside of being the love interest. It's all from Tim's POV, with Titans being the only even minor exception by deviating massivly. Hell, that seems to be a major part of his appeal for the writers, there's no need to put much work into the character in order to adapt him, he's just "the boyfriend".
Could Bernard become entrenched as Tim's love interest? Sure, but it's definitely not going to be the result of the adaptions so far.
