I think she did Rinne and Mao, but they didn't catch on like InuYasha. So might as well tap into the flow if you Naruto is pulling off a next generation thing with Boruto.
And Inuyasha is her best work that is suited for a continuation. Covers the most unique genres (supernatural, historical, romance, comedy, shounen, drama) and it still has an existing fanbase from the toonami days that'll rush to watch it, buy the merchandise out of nostalgia. Should be a hit.
