Yeah, I think Bard, Warlock, and Wizard makes sense. All three of them get access to feeblemind, for example. On the other hand, the 8th-level telepathy spell and the 5th-level Rary's telepathic bond spell are only available to Wizards, so if that's what its based on then maybe Wizard only makes sense. Sorcerer is probably the last one I'd give it to, but its feasible even if it would be a slight stretch, since they do get access to a few mind spells like psychic scream and detect thoughts.
