That's not a bad idea.
For reference, two posts in the "Jehovah in the NT" topic had 2,500 words/15,000 characters and 3,700 words/22,000 characters. 2,500 or 3,700 characters would already be several paragraphs long. That many words is a long article or blog post. You're not taking part in a discussion, you're delivering a lecture.
