This could work if you focus on a specific niche for every account you plan to manage.
Example niches:
- EDC items (every day carry)
- Fashion
- Religion (mainly christianity/catholicism)
- etc
However, twitter has become a cesspool of

, ever since you know who took over it.

You might reach your goal, if you appeal to the freaks and loonies that still orbit twitter.
And as people previously mentioned, automation alone might not do the trick, you'll probably need some manual interaction.
I have several twitter accounts that are semi-automated.
I schedule posts and let them run, while periodically checking in for manual retweets and likes.
I used to get decent traction with this method when Jack Dorsey was still around, not any more, though.
