Here's my list:
Peach T. (Breloom) - has 2 meanings: Could be a Mario reference, or the T can stand for her Ability Technician.
Atsuro (Porygon2) - based on a computer savvy SMT:DS character. I won't evolve Porygon2 further, as Analytic will become useless without Trick Room or a Lagging Tail.
Amazon (Nidoqueen) - she's a tough gal, and the name fits her.
Adenine (Reuniclus) - part of your average DNA strand as a nucleic acid. Should there be a male version, it'll be Thymine.
Celsius (Froslass) - part of a potential Tales spirits theme team.
Triton (Vaporeon) - The Little Mermaid, anyone?
Parvati (Steelix) - I dove into Indian mythology for that name. Alternative was Nagini (based on Harry Potter)
Selene (Musharna) - After the Greek moon goddess. Munna evolves using a Moon Stone. Indeed it fits.
Raine (Altaria) - Snuck a pun there, with how Altaria's wings are cloudlike...
