I've just finished the University of Oxford's online course on the wars of the roses. Lots of up to date thinking on the conflict and have lots of source material and interpretations. I've started putting some narratives on my website here https://schoolshistory.org.uk/topics/british-history/wars-of-the-roses Thinking of creating some activities based on these. Any areas that are particularly lacking at A Level? There's lots that can be used for KS3 too.
