Future Dub of Aftermath Of The Games/Intergration

I'm planning on making a dub of DarthLink22's stories Aftermath of the Games and Integration (I already got DarthLink's permission). I pretty much figured out what to do for some of the characters who don't have 15.ai (what I will be using for the dub) voices, but not every character yet.

• Here are some facts/plans I have.
• The Changelings will all be voiced by Micheal Huang as 15 will add BFDI voices and I figured that some characters that Micheal voices are perfect for the changelings. I also plan to use one of his voices for Chester A. Bum.
• Filly Starlight will be Starlight's normal voice pitched up
• To differentiate between Pony Flash and Human Flash, Pony Flash's voice will be pitched down to make him sound a bit older.
• For flash's family, I can use other MLP voices. I might use one of the CMC for his sister and Luna's voice for his mother. His father could also use Flash's voice but deeper than pony Flash's voice (plus it could be a nice reference to Ninjago where Vincent Tong voices both Kai and his father)
• Harmony is a bit difficult, but maybe I can use Celestia's voice and pitch it down and edit it (somehow) to sound more mystical.
• I have to wait until 15 completes the new characters, which might not be for a while.
