This might be a weird idea, but a way to synergize the blast feats with a character multiclassing into this class could be done with martial or spellcaster-specific feats? Like a 2-action focus cantrip that acts as the stanceless eldritch blast, or flourish feats for ranged and melee martials? Then throw in a "Special: this feat counts as a prerequisite" kind of line for stanceless and ranged/melee blasts.

Furthermore, I feel like the stances should a class feature. To gain access to a second stance, this could be handled like how druids and bards get their subclass-blending feats, except this feat is accessed at 4th level at least.

As for other features conduits can probably have that could be accessible via multiclass, I really don't know to be honest. 

Great class! The multiclass archetype does not seem to have much going for it though, considering that the majority of feats are geared towards eldritch blasts.
