Yes. She is one of my favourite female writers working today. She can inject some much needed personality into Diana (since new52 Diana is kinda boring) and provide those nice character moments that Captain Marvel had. As long as editorial lets her do her thing and not stifle her (as her Marvel run was with constant crossovers), she will do great.
And almost anyone with writing experience would do better than a novice nepotism eater like Finch.
