I'd say she should try something with mahou shoujo instead, all the tropes are easily transferable.Mainly because they keep trying to make an unorthodox combination of Shounen Battle manga and Yuri. These usually have conflicting target audience and you need the right magazine/publisher that caters to both. So far the only one that worked is MagiRevo and thats mainly because it was originally a light novel with existing groundwork.
There was issues with MajiGawa but it seems like that was more on the magazine side wanting drastic changes she didn't agree with. She just needs to find the right place for something like that.
