She doesn't do a bad job, but at times it sounds more like a parody of Harnell's voice than an impression.
I actually had an idea for a story involving bringing back Peri and Mel, following up on what had happened to them. My notion was that Peri married Yrcanos in a "making the best of a bad situation" sort of way. They would've had a son a few years later, and a few years after that, Yrcanos would've been killed in battle while their son was still a minor, with Peri becoming Regent of Thoros Alpha, and, with help from her late husband's trusted advisors, becoming a surprisingly effective administrator, helping the Alphans overcome the baleful influence of the Mentors.
Meanwhile, in a nearby time and space, we find that Sabalom Glitz had quickly grown weary of Mel quashing all of his "dodgy deals", has taken a starship, and "lit out for the territories", leaving Mel in charge of Iceworld. Mel also becomes a surprisingly effective administrator, and builds up a nice little trade empire for herself. She also finds a new target for her moral outrage - the corrupt Mentors of Thoros Beta. In aid of which, Mel leads a trade mission to Thoros Alpha, about whose Regent she has heard good things. While the mission is genuine, it is also a smokescreen for Mel to sound out the Regent regarding a possible alliance against the Mentors. When Mel and Peri meet, they soondiscover that they have "mutual friend".
The mission goes well, but there're two things that Peri and Mel don't know:
1)The Mentors are aware of their meeting, and its true purpose, and are already moving against them both.
2)Their "mutual friend", new wearing a new face, has just materialized on Thoros Alpha...
