Archmage Wild Arcana + Draconic Sorcerer Esoteric Dragon Variant Bloodline Arcana

[Rosk]

Hiya! So, in a game I'm running, I'm envisioning this might come up eventually.

Wild Arcana:
As a swift action, you can expend one use of mythic power to cast any one arcane spell without expending a prepared spell or spell slot. The spell must be on one of your arcane class spell lists and must be of a level that you can cast with that arcane spellcasting class.

You don’t need to have the spell prepared, nor does it need to be on your list of spells known. When casting a spell in this way, you treat your caster level as 2 levels higher for the purpose of any effect dependent on level. You can apply any metamagic feats you know to this spell, but its total adjusted level can’t be greater than that of the highest-level arcane spell you can cast from that spellcasting class.

Esoteric Dragon Draconic Sorcerer Variant Bloodline Arcana:
When selecting spells known, you can choose spells from the psychic class spell list. The psychic spells you select must normally be unavailable to your class. You can know only a number of psychic spells equal to the highest level spell you can cast from your class spell list, based on your current class level. When you’re casting these spells, they function as psychic magic instead of arcane. You use thought and emotion components (Occult Adventures 144) instead of verbal and somatic components when casting these spells.

Is it a correct reading that the sorcerer would be able to use wild arcana to cast psychic spells? Would the sorcerer have access to the entire psychic class spell list? Would the sorcerer be unable to use wild arcana to cast -any- psychic spell? I'm just a bit puzzled how best to read this.

My reading there says that no, they would not be able to use Wild Arcana to cast all psychic spells because the psychic spell list is only part of your sorceror spell list while you are selecting spells known (not at other times, for example, while activing spell-trigger items).
It is a little fuzzy, but I think the ones you select as spells known, however, WOULD be considered to be on your list, since you know them. It appears that nothing in Wild Arcana requires that you actually cast the spells as arcane spells, only that they be on your spell list for the class and be of a level that you can cast with that class.
