I'm curious how well that works. There's plenty of "epic", "anything goes" space opera already. What made The Expanse special for me was the gritty, realistic solar system period and not the things where protomolecule based tech was in full swing already.
I'd gladly have taken prequels actually, with only human tech and stories from the period before the protomolecule appeared.
