If there is little sunlight fescue wont make it. Look in your wooded areas next to a fescue pasture...
The endophyte issue is huge and you wont impact it either way plus it only impacts cattle to any degree. Bigger issue is fescue sucks for any wildlife.

Use orchardgrass or a native grass, seed it and drag it in next spring. Rely on legumes more than grass, korean lespedeza is a top choice, ladino clover also
