This Cyborg would roll over anyone in the BW division. End of the story.
A 135lb Cyborg, on the other hand, is a different thing. To get there she needs necessarily to lose muscle, and with less power she won't be as overwhelming as we know her now.
So this discussion is completely useless, they are in different categories and they won't fight together, if she stays in the current category she wins with everybody (including Ronda, including Holm), if she drops down then maybe Miesha is a problem for her, but not necessarily the main problem.
I still think Ronda will be used as a punching bag, I'm sorry but for me she won't ever get to clinch distance, and this is her main problem with Cyborg (and also the reason why I give some possibilities to Miesha). Holly hasn't looked good at all with Pennington, who dropped her with one punch. With Cyborg she won't resist, Cyborg is good in the clinch and good on the ground, and terribly strong (another important advantage Holly has in BW).
