Names for the Missing Planets

I have suggestions of my own and as Dr. Van Flandern was entertaining the possibility of using names from Greek mythology to contrast with the Roman names of the surviving planets as he told me in an e-mail, I am using Greek names.

A: Alkyoneus (eldest of the Gigantes)
B: Bia (meaning force or violent haste, god of force)

X: Hypnos
T: Thanatos (twin of Hypnos, children of Erebus (primeval god of darkness and shadow) and Nyx (goddess of night)

Alternatively, Bellatrix can be called Polemisti and Krypton Kydoimos (spirit of the din of battle). Alternatively, also, X and T could be dubbed Xeno and Tyche (goddess of fortune; in allusion to Tycho Brahe, or Erebus and Persephone.

How's about pepsi cola, coca cola, adidas and fords. Unethical but you'd get lots of money!

Planet T should instead be called Tarturus for the Greek god of the deepest darkest part of the undereworld.

Persephone is a name for Planet X so that one could be used, T stands for transneptunian so Transneptune could be used, and we could continue with the names Bellatrix and Krypton.

And LHB-A and LHB-B could be called Juno (consort of Jupiter) and Lua Saturni (early consort of Saturn or same as (later) consort Opis Consita), respectively, as it is more congruent for both partners to be Roman. Also, in this way, 6 of the original planets have masculine names and 6 have feminine names.
