If an aberrant mind sorcerer casts a spell from the Psionic spells feature, they may use the Psionic sorcery too
When you cast any spell of 1st level or higher from your Psionic Spells feature, you can cast it by expending a spell slot as normal or by spending a number of sorcery points equal to the spell’s level. If you cast the spell using sorcery points, it requires no verbal or somatic components, and it requires no material components, unless they are consumed by the spell
However, the Psionic spells feature allows you too
You learn additional spells when you reach certain levels in this class, as shown on the Psionic Spells table. Each of these spells counts as a sorcerer spell for you, but it doesn’t count against the number of sorcerer spells you know. Whenever you gain a sorcerer level, you can replace one spell you gained from this feature with another spell of the same level. The new spell must be a divination or an enchantment spell from the sorcerer, warlock, or wizard spell list.
If you "retrain" one of the spells from calm emotions too Tongues could you then cast tongues for 3 sorcery points instead of a spell slot and without using verbal or material components?
