You mean that she thinks like: if Tenma is with Harima it means that I'll be close to him too? This is possible. BUt for this some copld-heartednes is required, which Yakumo certanly lacks.

That will solve the problem only for the short amount of time - soon Harima will start to wishing for more and will break this balance; and Tenam will certanly become closer to Karasuma which will also break balance. Though you are right, Yakumo may think this way.
Or maybe she is still supporting True Oodou - she's pushing Harima and Tenma closer together so Harima can be happy, but without any intentions to change Tenma's heart. Harima is still happy when he's around her, right?
Tenma is pretty similar to harima when it comes to feelings, so I doubt you statment.
Well, Yakumo doesn't have to break True Oodou to get Tenma to like Harima. Tenma may be set on one person, but I think, unlike Harima, she's the type to be able to fall in love with someone else without having her heart broken. I can't see the same happening to Harima; unless/until Tenma rejects him, there's no Onigiri or Flag. He just can't see any other girls in the same way.
True she knows Harima better. BUt again, why is Odou better then True Odou? From Yakumo's point of view?
Yakumo knows her sister, and I wouldn't put it past her to be able to figure out who'd be better for Tenma even if Tenma herself doesn't really know. Besides, she actually knows Harima - she doesn't know Karasuma very well.
