That's so much overthinking for no reason. Just order 10 articles for $2 a piece, that's $20. That's nothing. Put 5 straight away, already optimized with links as well, schedule the rest, done. Move on. No idea why would you complicate stuff this way, but it's unnecessarily complicated, risky and all in all, makes no sense. Especially these days when indexation is quite a problem, using Word AI to just see if it will index is bullcrap.
If one of my clients came to me, that the domain I sold him is not getting indexed and he would show me a site with 2 Word AI articles, I would ask him whether he is okay in the head.
